Microsoft Teams

User Based Microsoft Teams

The standard installation that the user can perform, e.g. via the Microsoft365 Apps portal, is a user-based installation. In the Citrix environment, this is only recommended for desktop operating systems (pooled or personal desktop).

A User-Based Installation can be detected very quickly in the User Profile, because data are then located under AppData\Local\Microsoft\Teams.

This type of installation in a worker with server operating system has many cons:

No control over the installed version
Several different versions possible installed on the same worker
Complete data (~1 GB) are in the user profile

The possible scenarios for Seamless SSO are:

Pass-through authentication (PTA)
Password Hash Sync (PHS)
