i CANNOT ACCESS anymore to my school mail

Hi everyone,

I’m having an issue with Microsoft 365: an email address I used to have seems to no longer exist.

The address was cx.nxxx@amricci.onmicrosoft.com, and I can’t sign in or access it from anywhere (Outlook on the web/desktop/mobile). It looks like the account may have been deleted or disabled.

What should I check first, and who should I contact to restore the account or recover the mailbox (admin/tenant settings, user deletion/restore, license, etc.)?

Any ideas are appreciated.

I built a free local Thunderbird / mbox → PST converter looking for feedback

Hey everyone,

I’m an MSP technician, and I kept running into the same annoying migration problem: users had years of mail sitting in Thunderbird, Gmail Takeout exports, old POP accounts, exported Local Folders, or random .mbox archives and the path into Outlook / Microsoft 365 was usually either paid closed-source software or awkward Outlook automation.

So I built ContinuMail Converter, a free and open-source Windows tool that converts Thunderbird profiles and .mbox archives into Outlook .pst files.

Repo: https://github.com/ContinuMail/continumail-converter

It converts Thunderbird profiles and standalone .mbox archives into Outlook PST files, locally, without uploading anything or needing Outlook installed.

The big difference: it writes PST files directly with a from-scratch PST engine, instead of using the usual slow Outlook COM automation workaround, or paid SDK's.

t keeps the important stuff: folder structure, HTML bodies, attachments, dates, recipients, threading headers, and Thunderbird state like read/unread, replied/forwarded, starred, junk, and tags where profile metadata is available. Tags become Outlook categories.

I hope someone can find this usefull and i'd appricate all and any feedback.

Copilot Cowork vs Claude Cowork cost comparison

Interested in others who've compared running the same tasks with the same data and models in both claude and copilot cowork. Microsoft said it's 30-40% cheaper but we are finding that is absolutely false marketing. Our users are blowing through their limits the first day in copilot cowork. I've been running the same tasks across both platforms for comparison and everything costs drastically more in copilot cowork than it does in claude cowork.
What are you all seeing at your companies?
Please make sure you are voicing the feedback to your account teams at Microsoft.

Wasting A Small Fortune In Microsoft 365

Long story short, I had a client say, "We have more M365 licensed users than employees. Please help us find them."

It took me about a week to find all the waste (first time always takes forever). Now I've run the same steps for a dozen other clients (takes less than an hour now). On average, I've been able to save clients 22% of their budget.

Thought I'd share exactly how I do it.

There are 5 areas of waste in Microsoft 365:

  1. Remove licenses from disabled users.
  2. Remove licenses from inactive users.
  3. Downgrade licenses on over-licensed users.
  4. Stop paying for unassigned licenses.
  5. Redefine the license terms.

NOTE: I have the steps using the admin center, PowerShell, and a third-party app, but it's too long to re-post in Reddit. Go to Microsoft 365 License Audit to see all the steps.

Find Disabled Users

  1. Log in to the Microsoft 365 admin center.
  2. Users > Active Users > Export > Continue.
  3. Open the spreadsheet.
  4. In the Home Ribbon, click Sort & Filter > Filter
  5. Click the dropdown in the Licensed column > uncheck Unlicensed > click OK
  6. Click the dropdown in the Block credential column > uncheck FALSE > click OK.

Find Inactive Users

NOTE: You need to either have a Microsoft Entra P1 license or use a third-party app to get this data.

  1. Open Microsoft Entra Admin Center
  2. Users > Manage view > Edit columns.
  3. Remove, replace, or add so the only columns you can see are: Display name, User principal name, User type, Identities, Assign licenses, and Last interactive sign-in time. Click Save.
  4. Click Download users > Start bulk operation
  5. Wait for the success pop-up message to appear, then click the notification bell at the top of the page. Under the notifications menu, click Success!, and then select the [report name].
  6. Open the downloaded spreadsheet.
  7. Click Sort & Filter > Filter to enable the column filters.
  8. Click the drop-down in the assignedLicenses column. Uncheck any empty options, i.e., []. Click OK.
  9. Click the drop-down in the signInActivity column. Click Sort A to Z.
  10. Any users who have an empty signInActivity or a sign-in that was over 30 days ago can be safely disabled, and the license removed after the data is properly secured.

Find Downgradable Users

  1. Review the report located on the website, then click Export.
  2. Open the CSV in Excel.
  3. Next, download the Microsoft 365 apps spreadsheet by going back to Reports > Usage and clicking View More located under “Active users - Microsoft 365 Apps”
  4. Review the report and click Export.
  5. You can start by deleting everyone that you’ve already determined hasn’t logged on or is currently disabled.
  6. Add the filter by clicking Sort & Filter in the home ribbon > Filter.
  7. Add a column for Current Licenses.
  8. Copy the licenses from the How To Use The Admin Center To Find Inactive Users spreadsheet you downloaded earlier into the new column. Be sure to align the user names in both spreadsheets.
  9. Add a column for Microsoft 365 Apps.
  10. Copy the Last Activity Date column from the Pro Plus Usage report you downloaded above in step 7 into the Office 365 app usage spreadsheet you’ve been using. Be sure to align the new data with the appropriate users in the Office 365 app usage report.
  11. For each of the following columns, click the drop-down next to the column name and filter out any logins that have happened in the last month.
  12. OneDrive Last Activity Date
  13. SharePoint Last Activity Date
  14. Skype For Business Last Activity Date
  15. Yammer Last Activity Date
  16. Team’s Last Activity Date
  17. Microsoft 365 Apps
  18. The users who have not been filtered out are excellent candidates for Exchange Online-only licenses. You may want to double-check their usage of other apps before making any license changes on their accounts.

Find Unassigned Licenses

  1. Open the Microsoft 365 admin center.
  2. Click Show All > Billing > Licenses.
  3. On that webpage, you’ll see a list of all your licenses in your organization, along with a column labeled “Available Licenses”.
  4. Any number above 0 in the Available Licenses column is typically safe to remove from your organization with two caveats. Some licenses aren’t assigned to users through the Microsoft 365 admin center.

NOTE: Some licenses are consumed as they are used. For example, additional storage licenses for SharePoint Online may show as available, but removing them will decrease the amount of free space available in SharePoint Online and possibly cause a disruption to SharePoint Online usage.

Redefine The License Terms

Microsoft adjusted its pricing model, charging different rates for the same license based on commitment terms, billing frequency, or sector-specific eligibility.

  • The subscription length
  • Billing Frequency
  1. Go to the Microsoft 365 admin center
  2. Click Billing > Licenses > Select the license you want to review.
  3. Click ellipsis (…) next to the subscription > Manage subscription settings.
  4. You can view the billing settings right on this page.

Microsoft deleted the entire Org One Drive and won't even say sorry

So, let me start off by apologizing by some harsher words, but currently no better come to mind.

My mom runs a nonprofit organization. She is not very tech-savvy so I help her sometimes when she needs something. We setup a nonprofit licence for office 365 (I think it was business premium) around 3-4 years back and everything was working (as much as microslop stuff can). However the licence just stopped working on 14th of June, when I investigated I found ONE email warning that the licence will be suspended on May 1st.

However this email only arrived on that shitty .onmicrosoft address which is TOTALY USELESS. I can't log in to gmail, I cant even login to outlook desktop or mobile. The only way to check this email address is trough outlook on web. Which I mean COME ON. That shit is obviously really important that you discontinue the licence. Why cant you just send it on the secondary email too? BTW all invoices which are just 0euro arrive on that secondary email, nothing else comes there since its useless.

As mentioned 14th of june everything stopped working. I found the email and activated the new business basic licence which is now the free option for nonprofits. However the OneDrive contents were not present. Mind you everything important regarding her nonprofit business is stored in that one drive. So I started the neverending battle with useless Microslop support which are about as helpful as banging your head on a pavement.

After about 6th email where the useless guy just copy pasted shit out of a script while requesting me to do the same shit 20th time just different way (Every recovery step he recommended was opening one drive and checking if the files are there) I politely messaged him to fuck off and that it is obviously their backend issue and to stop making me stupid shit just because its in his script.

My question is, HOW can this even happen? Everything is the same, the accounts, the organization, the billing account, everything.

I know by law they're required to store the data for some additional amount of time. Does the countdown start from the 1st of May? If so how did everything work until the 14th of June without issues? Is any sort of recovery even possible? After the last email they just stopped responding all together. I received one email full of nothing burger so I don't count that.

Is someone here who can help me if the recovery is even potentially still possible?

Since the data is probably fucked, is there a way we can get from Microslop as apology for their stupid processes? I'm guessing not but you never know.

Graph API access denied

Our 35,000 user tenant is having trouble with all of our API calls from external apps. In troubleshooting, I am finding that anything that connects to SharePoint via the Graph API is getting access denied. The API connection succeeds, but subsequent calls to the target SharePoint site either times out or gets a 401 access denied error. I have a Sev A ticket open with Microsoft but haven’t received a response. Typically, when I don’t get a response from a sev A, it’s because there is an outage with something but there is nothing indicated on service health or any clues on X or subreddits.

Can anyone please test some graph api calls to SPO? Like a set command with a PNP.PowerShell or something you know connects to a SPO site?

I rebuilt my local M365 SOC Tool from PowerShell to a full Web App Now self-hostable with RBAC, SSO & much more

Hi everyone,

A while back I showed you my local Microsoft 365 SOC tool built in PowerShell. Back then it was limited to a single-user setup https://github.com/Mau2rice0/World-of-M365/tree/main/Security/SOC/M365%20Compromise%20Response%20Console

Well… I’ve been pulling all-nighters and completely rebuilt it from the ground up. It’s no longer PowerShell, it’s now a full JavaScript application and it’s absolutely fire.

You can now self-host it wherever you want:

  • On-prem
  • Azure
  • Any web server with at least 2 cores and 4 GB RAM

I’ll be releasing it in the next few days so you can host and test it yourselves.

What’s new & improved:

  • SSO support for additional users → no more manual logins
  • Full RBAC permission system
  • More RBAC roles coming: Analyst, Responder, Reader, Administrator
  • Azure Files Share integration for storing evidence and data
  • Significantly better performance
  • Security hardening
  • Fully automatic setup script that does the entire deployment for you

GCC / GCC-High compatibility is unfortunately not possible yet. I don’t have access to that environment and being based in Germany makes it pretty hard to get one.

If anyone has a GCC tenant they’d be willing to test with, I’d love to collaborate!

I’m planning to sink at least 35 hours into this project again this weekend.

If you have feature requests or ideas for what a proper M365 SOC tool should have, drop them in the comments. You guys know better than anyone what’s actually needed in the field.

Huge thanks to everyone who tested the earlier version:)

Can’t wait to get this into your hands.

Is a 70-tool Copilot Studio agent in Microsoft Teams a sustainable architecture for engineering workflows?

Our team is building a Copilot Studio agent in Microsoft Teams with around 70 tools across Jira, Confluence, Bitbucket, Databricks and Neo4j.

It can:

  • Create and update Jira tickets
  • Check pull requests
  • Run approved Neo4j queries
  • Retrieve Databricks job details
  • Create Confluence pages
  • Combine information across multiple systems

We also use Power Automate to notify Teams when Databricks jobs fail, so the long-term idea is for the agent to investigate incidents and take follow-up actions.

My main concern is context and maintainability.

In GitHub Copilot, I use local MCPs together with repository instructions, documentation, skills, prompts and guardrails. The agent already understands the codebase and project context.

In Teams, even with 70 tools, the agent may not automatically know:

  • Which repository belongs to a Databricks job
  • Which Jira project owns a pipeline
  • Which Confluence runbook is relevant
  • Whether the user means DEV, PREPROD or PROD

I am also unsure whether exposing 70 tools to one agent will cause tool-selection, security, testing and maintenance issues.

Would it be better to use an orchestrator with specialized agents for Jira, documentation, source control and data platforms?

For people using Copilot Studio in production:

  • How many tools does your agent have?
  • Does reliability decrease as the tool count grows?
  • How do you manage project context and permissions?
  • Do users still need to provide a lot of context manually?
  • Is this architecture worth continuing to invest in?

My current view is that Copilot Studio is useful for shared operational workflows, while GitHub Copilot remains better for repository-aware coding and debugging.

Cutting through the noise on microsoft azure support vendors, what’s actually real?

I’ve been burned enough times by vendor pitches that I’ve developed a pretty strong allergy to anything that sounds like a press release. So I’ll be direct about where I’m at: we’re a 450-person logistics company running most of our workloads on Azure, and our current Microsoft support arrangement is costing us a lot for what feels like very little. Slow ticket responses, generic troubleshooting steps that any engineer could Google, and a renewal conversation that was basically ‘same price, fewer perks.’

I started looking at third-party Microsoft Azure support options a few weeks ago and immediately hit a wall of marketing fluff. Every vendor claims faster response times, deeper expertise, significant savings. It all blurs together. What I actually want to know is: did anything concrete change for your team day-to-day? Not the pitch, not the case study on their website, just the honest version.

Specifically curious whether anyone has been through a real P1 incident with a third-party provider and what that experience was actually like. That’s the moment where support quality either holds up or completely falls apart, and no vendor is going to tell you the ugly version of that story in a sales call.

We have users whose Microsoft 365 sign-in is blocked and who no longer have an Exchange Online mailbox license. However, when email is sent to a Dynamic Distribution List, Exchange still attempts to deliver messages to these users, resulting in undeliverable (NDR) messages.

Is there a way to create a dynamic distribution list only for current employees?

Before I ditch 365... Any advice or fixes?

I'm talking single user frustrations and very small business. Not enterprise.

  1. Outlook app on Android calendar view shows dots on days that do not have any events. It appears to show event dots on the day before. For all day events.
  2. Rules configured on any thick client are only for that client. Have to reconfigure them on each device. Or attempt to use web client to setup rules. I've found web client setup does not filter down to thick clients well.
  3. Emails seem to take a long time to show up. Frequently have to do multi-factor and codes can sometimes take 3-10 minutes to arrive. Rarely experience this on my "throw-away" Gmail account.

Aside from these issues... I find myself wondering what value I'm getting out of a rather expensive yearly subscription?

Red arrow points to the DOT i'm talking about. The green arrows are pointing to where the actually events are scheduled. The 8th has NO event. The 9th has an event. The 4th has no event, the 5th has an event.

The 14th has no event, the 15th has an event.

The DOT is showing up on the day BEFORE the event takes place. It's almost as if the code sees "All Day" and whatever times they are using behind the scenes (none are shown when you toggle "All Day" is causing the dot to show up on the previous day?

Introducing 365 Launcher - free and open source launcher for M365 admins and users

Hi all, so my launcher has been out for some time, here are some of the features:

  • Designed for M365 admins and power users
  • Quick access to all M365 admin portals and web apps
  • Reduce number of open tabs - if you already have a tab open, it will switch to that tab rather than opening a new one
  • Search - very fast to launch apps, just type to instantly filter, keyboard down to highlight the matching tile, hit enter.
  • For M365 business and enterprise only, not for home or personal accounts.
  • No sign in required, no data is captured.

I'd really appreciate some feedback, and possibly even a review or two!

Add from the Chrome store:

50 to 100GB Storage Quota Changes (July/August/Sept) - How to know?

Microsoft has announced that storage for Business subscriptions will increase from 50GB to 100GB. This means any customers with Exchange Online Plan 2, where the license is only being used for additional storage, will no longer need it.

Microsoft has said this will roll out to all tenants over July, August, and September. For customers on annual commit, especially those renewing during these three months, we want to move their NCE to monthly commit so we can cancel it once we know.

Does anyone know if there is a way to determine whether this rollout has been applied to a tenant, other than removing the EXC P2 licenses and checking whether it shows 100GB? I assume it would not show 150GB if it has already been deployed.

There is quite a bit of work involved in this, so it would be very helpful if there were a way to confirm whether this has happened for each tenant.

Microsoft 365 license requests notifications by email

Hi everyone,

In our Microsoft 365 tenant when a user submits a license request, it correctly appears in the admin center under “License requests”, but no email notification is sent to admins o license administrators.

At the moment we don’t have any workflow, Power Automate flow, or alert policy configured.

Is this expected behavior, or am I missing a setting that enables email notifications for license requests?

If this is not supported natively, what’s the usual workaround you use to get notified via mail when a request is created?

Thanks.

Are all my files going to be deleted because I'm losing access to a university email?

I wanted to export my email, so I signed into outlook on my PC. Huge mistake, it made One drive ruin all my file locations and break everything on my PC. I signed into one drive with my personal account, left outlook with the school account. Do I have to worry about interference with outlook and one drive? I don't want to lose my personal files I had prior to signing in because I signed into outlook. From what I can tell one drive only has the personal account, when I clicked add account, it automatically filled in the school account, but I didn't sign into it. I checked one drive on the website, the school isn't showing anything, but I just want to be careful. I never used one drive with the school, I'm worried about interference.

Anything else I should be concerned about? Are my files at risk of deletion? Any general advice? It seems archiving from outlook is not easy.
