We are using Citrix and FSLogix to manage a shared, multi-server Windows Datacenter Server 2022 (fully patched) environment. I have followed the instructions outlined here: https://learn.microsoft.com/en-us/microsoftteams/new-teams-vdi-requirements-deploy. I have upgraded FSLogix to 2.9.8716.30241. Uninstalled the Classic Teams Wide Installer and installed the new Teams app. I have also deployed the registry key (ProcessWhiteList). Teams will launch just fine on first launch. However, after a user signs outs of Windows and signs back in, New Teams will not launch. New Teams fails with a message: msteams_autostarter.exe "The parameter is incorrect ". If I clear Edge cache, I can launch Teams again. But just for this session. Logging off/logging in brings the error back again. I am wondering if FSLogix is truly saving all of the data in %LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache. When I compare the folders that exist on the server when I am logged in vs. the folders on the profile server when I am logged out, there are a few folders missing. When logged in to Windows, there are "AC, AppData, SystemAppData and TempState" folders - these folders do not exit on the profile server. Uncertain if this is the problem or not. Any advice how to resolve the "The parameter is incorrect" issue? Thanks.
