Good afternoon,

We have a customer using Horizon non-persistent RDSH sessions integrated with DEM and AppVols.

We are trying to achieve persistency in Teams/OneDrive credentials across RDSH sessions using DEM, but nothing seems to work.

VMware support is trying to help us for months with no success as when a user logs to a different RDSH server from time to time it asks again for credencials or returns an error.

I attach the best Teams DEM config that we have tested applied for a set of users:

[IncludeFolderTrees]
<LocalAppData>
<AppData>\Teams
<AppData>\Microsoft\Teams

[IncludeRegistryTrees]
HKCU\Software\Microsoft\Office\

On the other hand, we have tested FSLogix Apps with DEM agent removed but we are not able to retain user credentials. I attach redirections.xml:

<?xml version="1.0" encoding="UTF-8"?>
<FrxProfileFolderRedirection ExcludeCommonFolders="113">
<Excludes>
<Exclude Copy="0">AppData\Roaming\Microsoft\Teams\media-stack</Exclude>
<Exclude Copy="0">AppData\Local\Microsoft\Teams\meeting-addin\Cache</Exclude>
</Excludes>
<Includes>
<Include>AppData</Include>
<Include>LocalAppData</Include>
</Includes>
</FrxProfileFolderRedirection>

A colleague of mine have read that the problem could not be within DEM or FSLogix but in Teams/OneDrive themselves, as Microsoft has changed the way that credentials are saved.

Can someone put some light in this weird behaviour?

Thank you.
