The mail client landscape is shifting.

​

Classic Outlook is entering its long sunset phase, while Thunderbird is becoming much more relevant again for organizations looking for open, sovereign alternatives.

For the Nextcloud ecosystem, this is a strategic opportunity.

Many organizations will not just ask:

“Which mail client replaces Outlook?”

They will ask:

“How do we keep file sharing, meetings, attachments and daily collaboration workflows under our own control?”

That is exactly where Nextcloud + Thunderbird can become a strong open-source stack.

With NC Connector, ( https://addons.thunderbird.net/de/thunderbird/addon/nc4tb ) I’m trying to close one of the practical gaps:

Nextcloud Talk meetings, secure file shares, attachment automation and centrally managed email signatures directly inside Thunderbird.

Not as a separate browser workflow, but where users actually work: in mail and calendar.

I think there is a bigger story here:

“Nextcloud + Thunderbird: the sovereign open-source mail stack.”

What does Thunderbird’s renewed momentum mean for Nextcloud users?

And how can the ecosystem make the move away from Outlook Classic easier for organizations that want control over their data?

NextCloud v Microsoft 365 basic

Hi, I’m in a quandary about choosing between NextCloud and Microsoft 365 basic for personal usage.

I like the idea of sovereignty over my data in NextCloud and that it is based in Europe (as am I). In my case I’d be opting for hosted NextCloud (possibly with TheGoodCloud https://thegood.cloud/ ). For around €2 per month (annual payment) I’d get 10Gb of storage with the basic office type apps . However I’d still have to opt for an email service which is an extra cost , say another €20 or so. Apart from using NextCloud web interface as a Mail client the email wouldn’t otherwise be integrated into NextCloud - I’d also have to get an Android app for calendar etc.

With Microsoft 365 basic for approx the same €2 per month I get adfree email , 100Gb storage, all products integrated into one interface , Android and iOS apps included and also some additional security . Also I’m not sure how secure NextCloud is and certainly it is hard to imagine that TheGoodCloud/Nextcloud having the same resources available to them as would Microsoft ?

I do appreciate the privacy aspect but on the other hand Microsoft are legally bound to observing GDPR. Can anybody help convince me that NextCloud is the better option ?

Is Nextcloud enough for company of 150 people?

I've been using nextcloud for nearly a year on my own, connected couple of devices in my family to my local server and its great. However recently one of our customers requested on-prem file sharing service and I thought of Nextcloud. What I was wondering will community edition will be enough for this company of 150 people. At max 30 TB of files will be stored and shared through also user management with LDAP integration is a must. Whats your take on this? Thanks

Getting Unraid Nextcloud docker to see SSL certs in NPM docker

Novice here on this matter. I have NPM running in a docker in Unraid as well as Nextcloud. (Slowly trying to get SSL working with Nextcloud). (Using letsencrypt with DuckDNS - internal use only).

I have my Nextcloud docker template pointing to this path /mnt/dockers_ssd/appdata/NginxProxyManager/letsencrypt/ with the label being SSL Certificates and the Container Path being /etc/ssl/nextcloud.

Will Nextcloud read the certs this way?

Best practices for small company

I was wondering when using a hosted instance like with for example hetzner what are must have settings or apps installed through the UI for a small company for let’s say 50 people?

- 2FA for admins at least?
- shared settings

….any advice? Or is there documentation somewhere? I am not talking about the technical backend like backups etc.

Nextcloud Hub 26 (34.0.1) Where did my apps go?

Really. I can't see your, active or disabled apps any more with "Could not load apps list. Please try again later". Log is telling me "InvalidArgumentExceptionValue (skynettechnologiesallinoneaccessibility) for app is too long (32)"

Tried google and nothing. Ran an occ repair. No fix.

I'm not impressed. I don't mind tinkering and have fixed many issues over the years but when I'm getting nothing from google to even indicate where to look that's a problem. I'm on stable for a reason. It should be stable. This is not stable. It still works but I can't do anything with apps.

Any help or pointers in the right direction would be appreciated.

Debian latest everything, no docker.

Stuck install

I'm following the GitHub instructions for AIO and every time I try it seems to get stuck.

sudo docker run \ --init \

Initial startup of Nextcloud All-in-One complete!

You should be able to open the Nextcloud AIO Interface now on port 8080 of this server!

E.g. https://internal.ip.of.this.server:8080

⚠️ Important: do always use an ip-address if you access this port and not a domain as HSTS might block access to it later!

If your server has port 80 and 8443 open and you point a domain to your server, you can get a valid certificate automatically by opening the Nextcloud AIO Interface via:

https://your-domain-that-points-to-this-server.tld:8443

I can't actually access the login page and the only way to access the terminal is to remove the container. Any suggestions?

Far sembrare nextcloud come liquid glass/winodws 7 aero

Ciao a tutti, c'è un modo per rendere Nextcloud simile a Windows 7 con le trasparenze e il logo di Windows 7 che si illuminano quando ci si clicca sopra? Non mi piace il design predefinito, preferirei quello descritto. Qualcuno di voi ha già un tema pronto? O un codice CSS da incollare? Ecc...

Un'altra domanda: qualcuno di voi ha un pacchetto completo di icone originali di Windows 7 in HD? Nell'immagine si vede come appare ora. Questo è il posto giusto per chiedere?

Built a Microsoft SharePoint → Nextcloud File Sync plugin — open source, recursive, delegated OAuth2

Hey Nextcloud community 👋

I'm Thomas. A few months ago I posted about a Google Calendar sync plugin I built while migrating clients off Google Workspace. A few people asked: "what about Microsoft?"

Well, here's the answer. This is the second plugin in what I'm building as a complete cloud-to-Nextcloud migration and sync suite.

Just open-sourced it: https://github.com/ianustec/nextcloud-microsoft-sharepoint-sync

The problem: clients share SharePoint/OneDrive folders with us. Files need to land in Nextcloud Group Folders automatically, without asking clients to change anything on their side — no API keys, no special setup on their tenant.

The solution: delegated OAuth2 with a single service account. You authenticate once with an account that already has access to the shared folders, and the plugin does the rest.

What it does:

📂 Recursive download of any SharePoint or OneDrive folder and all its sub-folders

🏗️ Replicates the full folder hierarchy inside a Nextcloud Group Folder — idempotent (existing folders are reused, never duplicated)

🔄 Change detection by size + modification time — unchanged files are skipped on re-runs

🔐 Delegated OAuth2 via Microsoft Graph — no changes required on the client's tenant, works with guest/external access

🔒 Refresh token and client secret encrypted at rest with Nextcloud's ICrypto

📊 Live summary report after each run (downloaded / skipped / folders / errors)

⚡ No external Composer runtime dependencies — uses Nextcloud's built-in HTTP client

Three deploy modes (k8s, Docker, bare metal):

./deploy.sh k8s     my-namespace nextcloud
./deploy.sh docker  nextcloud
./deploy.sh local   /var/www/html

This is part of a broader effort I'm working on: a suite of open-source sync and migration plugins for Nextcloud, covering the most common cloud services companies are trying to move away from. The Google Calendar one was the first, this SharePoint one is the second — more are coming.

Happy to hear feedback, bug reports, or feature requests. If you're in the middle of a Microsoft → Nextcloud migration and hitting other blockers, let me know — it might shape what I build next.

Small company

Hey there,

I am looking to replace an old NAS server with Nextcloud, and have some questions.

The company is approx 10-15 people

They simply use the NAS as network shares, and have 2-3 shares in total:

Common (everyone can access it)

Finance (only for the accountant and the 2 owners)

Management (Only for the 2 owners)

They dont want to host anything themself anymore, so the plan is to use a hosted Nextcloud solution.

I have briefly looked at the vendor list at Nextcloud, but they seem to all be licensing per user - not the storage.

Is that the only option available, to license per user? Today they all access the common share with the same user, and then the 2 owners and the accountant have their own account, that grants them extra network shares.

They are used to a network share - is the Nextcloud app the right solution in the future, or is WebDAV stable to use for them? - simply because it looks like a network share

How does Nextcloud handle, if two people opens the same file - on a network share, it locks the file - but if we use the Nextcloud App, then the files are present locally, and only after its synced after an edit, then a file conflict will occur - or not?

They dont want the email, calendar, whiteboards, etc - just simple cloud storage with MFA, that are easy and simple to use.

If anyone can recommend a provider in northern germany / Denmark, that would be perfect - they want zero maintenance (managing SSL certificates, perform updates, etc), but can easily create new users, reset passwords, etc.

Thanks in advance 😄

Direct migration possible from OwnCloud 10.16 to NextCloud 34?

Sorry if this has been asked before, I couldn't find any info on this:

According to https://docs.nextcloud.com/server/latest/admin_manual/maintenance/migrating_owncloud.html

direct migration is possible from OwnCloud 10.16 to NextCloud 34 bar an intermediate php upgrade to 8.3 or 8.5.

Is that actually true or a mistake in the documentation?

Previous versions of NextCloud, e.g. 33, and the documentation in the stable branch at

https://docs.nextcloud.com/server/stable/admin_manual/maintenance/migrating_owncloud.html list 25.0.13 as the latest possible target version for an OC migration.

nextcloud folder mapped to my desktop.

I opted to have my nextcloud folder mapped to my desktop. Every so often my windows 11 will write bullshit files into my nextcloud folder for no reason. Is there a way to stop windows 11 reaching into my nextcloud folder just to write trash into it?

Edit: The trash that I am talking about: desktop.ini, Music, Video, Searches and many others I don't give a rat's ass about. As a stop gap in the meantime... I have a cron job running to delete bullshit off my nextcloud every morning at 7... I do really need a solution to this bullshit.

Oh and this NTUSER bullshit. I don't know what it is and I don't care. it doesn't belong in my personal locally hosed storage!

Modern Android Calendar App (for Nextcloud)

Hi guys. I wanted to show the nextcloud community an android calendar app I made, because I switched from US-services like Google Calendar to Nextcloud recently and was unsatisfied with the all the available calendar apps which would natively work with my self-hosted Nextcloud calendar. The app works natively with CalDAV and should be perfect for self-hosted calendars.

I would be really honored if some of you’d like to try it out and maybe even give me feedback here or on github.

Nextcloud Calendar

So I got the android app for Nextcloud Calendar but when I try to use my hostname for my self-hosting server, even with the CalDav URL, I am still getting a "Could not connect: Network Request Failed". Did anyone have any luck trying or is this not available with Self hosting?

Nexcloud not working at all

Apologies beforehand that english is not my native language.

I managed to install nexcloud to my home server, with intention that it would be MY cloud in MY server. And installed android app to my phone. That worked fine, sort of.

Then i wanted to see what else it would do for me. I logged in to my server (with firefox) as nextclud admin. I got in where there is possibility to install more apps. I clicked calendar and tried to install it. It asked my password, and then nothing. It did not install the calendar to my nextcloud.

So i wondered that my NC server setup did not go well. On youtube I found good tutorial howto set it up correctly. So I removed my NC directory fom /var/www/html purged my mariadb, php and apache setup vith sudo apt purge command, did sudo apt autoremove and rebooted the machine.

After the reboot I followed exactly this youtube video omitting the Linode part, domain name part and ssl stuff. And got it installed, but I can not install any NC apps. Only via sudo occ command in ssh command line. In NC webpage it jus asks my admin password and does nothing.

My server has only three users me, my wife and root.

My NC admin is just admin for NC, no sysytem account.

My mariadb user is just mariadb user, no system account.

And I like keep those three things as they are.

So howto proceed or just forget nextcloud and use syncthing?

Nextcloud - account disabled

I've been searching for some hours now, but cannot find a solution to a rather common problem.
I was at work and needed access to my nextcloud calendar. I typed the passwort wrong a few times and now my account is disabled.
I *think* that account was also the (only) admin-account.

My nextcloud is running as an add-on (Fabio Garavini) in home assistant.

No solutions I found so far worked, because i don't have docker, podman, I don't know how i can access the DB and also AI is running in cirles by now.
Resetting a passwords obviously sends a mail to that nextcloud-account that i cannot access - if a mail is even sent because i never set it up.

So... what's an preferable easy and non-intrusive way to reset the password and access my nextcloud again?

When you leave Nextcloud working for more than 2 days:

Some logs are just honestly useless and shouldn't even appear, like image preview generation. Mine are working by the way, I know how to fix it too (I had to, a ton of times)!
