So I have Teams auto logging in on my Windows 7 Horizon/virtual desktop using the proposed DEM configuration outlined above.  However, this same configuration is not working for the Windows 10 Horizon/virtual desktop.  What does the DEM configuration need to  look like for Teams to auto login on my Windows 10 virtual desktops?  

Hi guys,
we investigated into this issue and we found a solution.

Shared Settings for O365:

Include the following into IncludeFolderTrees:

With this config it works fine for us

@MeyMath ,

Thank you for the post.  So I added the above to my DEM config file for Teams for my Windows 10 virutal desktop and I have some different results.  Now, when I login to the desktop I am presented with the Login screen showing my Account and a Sign In button (attached).  When I click Sign in, it takes me directly into  Teams without having to put my password in.  So this is different behavior, maybe better since I don't haVe to type a password but would still prefer having it automatically logging in. I must be missing something....

We changed in the meantime the settings to the following one, because Microsoft updated the AAD Broker Plugin and schanged the version number:

All my customers and me are working fine with this configuration

Thank you for the response. 

I went back and looked at my Config file for Teams in DEM and discovered I was missing the IncludeFiles section.  I added it and the first time I logged in it prompted me to click Sign IN on the screen where my userid was already filled it and then I had to type my password in.  I logged out of the desktop, logged back in and now Teams signs in automatically.  I have done this twice now and so far so good.  When I get into Teams, it takes me to the Teams section instead of Chat.  This is not a big deal but just curious if there is a way to make the default section Chat. 

Currently, my config file looks like this.  I left all of the entries in the IncludeRegistryTrees section which I know you have taken out.  Shall I remove the entries as you indicated?

I am working with a different customer on a Teams issue where a few of the users are getting an error when Teams attempts to start.

"There's a more permanent way to sign in to Microsoft Teams. If you're having trouble completing the process, talk to your IT admin."  See attached for complete message. 

I implemented this in DEM for them but some users are still getting the above error.  I looked on a horizon desktop and see all of the teams information in the C:\Users\rwulffenstein\AppData\Roaming\Microsoft\Teams directory which is not included in DEM.  Should it be?

By the time everyone gets to a final working solution we should start a Team VDI consulting company! lol 

Kudos for everyone to their help and respectful replies. I'm going to be tackling updating teams soon after we upgraded vSphere and Horizon and remembered just how frustrating it will likely be to get this all working again.
