We are dealing with an issue where it seems Outlook 2024 LTSC is no longer fully compatible with all Microsoft 365 services. For 365 user accounts created after June 2026, the Apps/Addins in Outlook no longer work. Older 365 accounts on the same device work great. This is causing our companies CodeTwo 365 software to stop working for new employees. I have already created a supportcall at Microsoft but there must be more people experiencing the same issue.
In Outlook there is a button called "All Apps". When clicking that it just says "You don't have any apps yet". Mind you these apps works great in Webmail and also in Microsoft 365-Apps for enterprise.

We currently use a few older Adobe Creative Cloud accounts that were created years ago. Each account is linked to a credit card for billing.

Each account has one of these two products:

Photography Plan (20GB) that consists of Photoshop and Lightroom
Creative Cloud App Apps (100GB)

Adobe is now asking us to consolidate the licenses in a Team account for easier billing etc but I did notice that the Photography Plan might no longer exist. What are the risks of this consolidation when it comes to monthly cost of licenses? Or even losing access to this specific plan? The Photography Plan we currently pay for is extremely cheap compared to a separate Photoshop or Lightroom license it seems.

Has Microsoft changed anything recently that would explain the following? I'm troubleshooting a RDS farm using Office 2024 LTSC where suddenly (on new user accounts only) none of the 365 add-ins in Outlook (classic) appear. They do work when using a laptop with the Microsoft 365-Apps for businesses. It feels like Outlook 2024 LTSC is no longer able to "talk" to 365 correctly.

Existing users that were created months ago have no issues using the Outlook add-ins on that very same RDS farm using Outlook 2024 LTSC. When checking the add-ins it simply says "You don't have any apps yet - Select Add Apps to browse and install apps."

These 365 apps (addins) work great in webmail for 365
