Think I've narrowed down the *"To schedule a Teams meeting, make sure you're signed in to Teams.*" error when running the Teams V2 Meeting addin (TMA) on Server 2019. TMA was installed with ALLUSERS=1 as per MS article. Removing the "Onedrive" DIR from the FSLogix ODFC container prior to login (created in Server 2016 with build 60056) seems to then restore the drop down arrow and full functionality of the TMA. I'm currently using 60056 in Server 2019 until HF4 is green-lighted for correct Teams v2 support. No clue why the OneDrive data in ODFC would be causing carnage with TMA!?!? Open to suggestions. Rather not have to put forth some intervention when looking to go live with Teams V2 when its cooked.

Works out of the box on Windows 2022 if using NeverRed for the installation.

Yeah because I tinker so much on it 😅 😅 😅 if u need more information send me a dm 😅 😅

Yea NeverRed is my go to as well. I have my own scripts, just for my knowledge. But I love NeverRed.

Still seeing this issue with HF4. However, now were persisting v2 data into ODFC, TMA starts to work correctly on subsequent logons, just not the initial login to a v2 based box UNLESS... the Onedrive DIR is deleted from ODFC prior to login... Have you seen this @Jason Parker? I think our userbase will be a little salty if they have to login / out / in to get the TMA to work as intended. Thanks.

Haven’t seen this and should be investigated with OD and Teams

Thanks Jason. I'll get a ticket raised.
