When we run AVD sessionshost with Windows 11 and fslogix, the users get random problems with Teams, Outlook and Edge. This occurs only when the vm size is a version 5. It doesn't matter which version 5 size (Exads_v5, Eyds_v5, or Dxds_v5). Pproblems we experience: teams doesn't start or the pane where the message are diplayed keeps empty Outlook ost problems, or certificate warning Edge random error pages We see no events, which declare these problems. When we disable fslogix and users have a local profile there are no issues, there is also no issue when we resize the sessionhost to a version 4 vm size (Exas_v4, Exds_v4, Dxds_v4, etc). Are windows 11 sessionhosts compatible with vm sizes version 5?

Outlook ost problems, or certificate warning
Edge random error pages

We see no events, which declare these problems.

When we disable fslogix and users have a local profile there are no issues, there is also no issue when we resize the sessionhost to a version 4 vm size (Exas_v4, Exds_v4, Dxds_v4, etc).

Are windows 11 sessionhosts compatible with vm sizes version 5?

@Sander Walraven

So, when you use a v4-VM with FSLogix enabled it works?

Are you using the latest version of FSLogix and also have the latest CU installed on Win 11?

@vipullag-MSFT , Yes latest build (22000.613) and Fslogix (2.9.8111.53415). For troubleshouting we are using a clean Microsft Marketplace image, even then we have problems met v5-VM.

Thanks for sharing the details.

Can you share more details on what specific issues you have with Teams?

I see you shared this "- teams doesn't start or the pane where the message are diplayed keeps empty"

Apart from these can you add more details.

We also experienced this exact issue and found the problem to be with the Azure file share regardless if it was standard or premium. FSLogix user profiles are affected as the Azure file share is problematic.

Reading data from the share worked as expected, however, writing data was very poor with speeds ranging from 200KB/s to 70MB/s. Reverting to a v4 VM saw speeds return to 300-400MB/s.
