Teams outlook add-in


Hi Team,

Could you please help me understand how the Teams Outlook Add-In works and can be controlled via GPO?

 a. how exactly what the teams client does to install the Teams outlook add-in and expose it in Outlook
         i. i.e. any registry settings applied etc…
         ii. How the process potentially impacts GPO based management of the add-ins as managed through resiliency list in GPO based add-in management
     b. If entirely managed via Teams Meeting Policies, can the outlook client still disable the Teams add-in if it is slow to load/crashes/other
                c. Is there a need for specific config in 'resiliency' GPO Add-in config to allow the Teams Meeting Policies to fully manage the Teams Outlook add-in


Thanks in Advance..

Regards,
MS

Hi @MS-5605

a. how exactly what the teams client does to install the Teams outlook add-in and expose it in Outlook
i. i.e. any registry settings applied etc…
ii. How the process potentially impacts GPO based management of the add-ins as managed through resiliency list in GPO based add-in management

According to the information in this document, the registry below is related to the Teams meeting Add-in in Outlook:
199442-1.png

I tried testing in my lab and also noticed that the registry above would appear once I sign in Teams as a user who has a Teams Meeting policy that permits the Teams meeting Add-in in Outlook.

Regarding your concern in terms of GPO based add-in management, based on my test, as other outlook add-ins, you can also manage the Teams meeting add-in through the resiliency list. More details, you may refer to System administrator control over add-ins.

b. If entirely managed via Teams Meeting Policies, can the outlook client still disable the Teams add-in if it is slow to load/crashes/other

Yes. When Outlook add-in is turned on in the Teams Meeting policy applied to a user, the registry mentioned above would be applied when the user is logged in Teams, with the value of LoadBehavior set to 3, which means the Teams meeting add-in is set to load at startup. But if any error occurs, like other add-ins, the Teams meeting add-in will also be disabled by the Outlook client.


c. Is there a need for specific config in 'resiliency' GPO Add-in config to allow the Teams Meeting Policies to fully manage the Teams Outlook add-in

Not quite sure about what you meant by "allow the Teams Meeting Policies to fully manage the Teams Outlook add-in", but if you just want to control whether a user can use the Teams meeting add-in in Outlook, there'e no need to make additional GPO settings.

Hi @YukiSun-MSFT : One last clarification,

  1. In the TAC, do we still need to "Allow the Outlook add-in" in the Teams Meeting policies \settings when we control via GPO?

Thank you,

Regards,
MS

Hi @MS-5605,

If you just want to prevent users from using the Teams meeting add-in in their Outlook clients, you can turn off the "Allow the Outlook add-in" in the Teams Meeting policies \setting. Otherwise, that is to say, you want the users to be able to use the Teams meeting add-in in Outlook, but would like to use GPO to control other add-in behaviors, you'll need to make sure "Allow the Outlook add-in" is turned on in TAC.
