Hi everyone, I want to check is anyone faces this issue. Again it happened after patching. We are running Omnissa Horizon 2603+DEM+Appvolume+FSLogix (version 2.9 profile+ODFC) on Windows 11 23H2 (we are in a process of testing to upgrade to 25H2) instant clones. We do see now in Teams the following message after September patching. We tried to delete the Teams Cache and all configs no luck. Also if we delete the ODFC container the banner is gone, but it come back on the next login. Same with brand new profile. We also tested on the 25H2 (with FSLogix 26.01 CU1 and 26.08 thinking about outdated 2.9 version) and is happening the same. It seems that Teams is working, but for some reason is not recognizing the Windows edition properly. After checking in the vdi_debud.txt Teams logs it is show up the correct detection of the OS as Windows 11 enterprise. Really not sure why is prompting for server 2025 on Windows 11. I'm using using the script v2 from Koetzing to deploy Teams thru MDT Automated method. Thanks

Thanks. I didn't check in that channel. Thought it was September patch issue. Interesting It happened on the 25H2 as well.

Windows 11 is supported, so it could well be a little bug.. they seem to hand these out like candies

so the only hope will be Microsoft to fix that behind the scene. Also I can't find the suggested setting in the latest Teams to test if the banner will be suppressed.
