Teams outlook add-in

Question

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

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:

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.
