I need to enable via GPO or registry the Microsoft Teams "Register Teams as the chat app for office" function. Is this possible??

Is there a workaround or do the users need to manually do so?

Either manually or by setting the users to teams only mode

@BENT17 

 

I struggled also upon this, and figured out that you have to build a  user settings GPO which adds (if not exists) or changes the REG_SZ value named DefaultIMapp to Teams in the following key:

HKEY_CURRENT_USER\Software\IM Providers

I've testd and verified that when i deselect the "Register Teams as the chat app for Office" option in Teams preferences, the complete DefaulIMApp disappears and vice versa.

 

This can also be done by editing the desktop-config.json file in:

%USERPROFILE%\AppData\Roaming\Microsoft\Teams\desktop-config.json

 

change:

"registerAsIMProvider":false

to:

"registerAsIMProvider":true

 

To automate this you can use the following powershell line:

((Get-Content -path "$env:userprofile\AppData\Roaming\Microsoft\Teams\desktop-config.json" -Raw) -replace '"registerAsIMProvider":false','"registerAsIMProvider":true') | Set-Content -Path "$env:userprofile\AppData\Roaming\Microsoft\Teams\desktop-config.json"

So far my contribution to this community :)

@adam deltinger  We went to Teams Only mode last night and our users are having to manually make the change in Teams application. Now we are look at the GPO option mentioned by @mhvanderhoek .

Give it some more time and it will probably fix itself

@adam deltinger  Ok--We will wait a full 24 hours and see it it fixes itself.  Would take longer than that to get the approvals to push out a GPO change.

Hi @SusanMcClements   I'm curious if this issue was resolved using Adam's advice to give it 24 hours.
