Outlook Addin not appearing in Windows Outlook 365

votes

My addin is working in outlook web client as expected but not showing in Outlook 365 Windows client (Ribbon Buttons not appearing).

I double checked the manifest, it is working as expected on another tenant in Outlook Client (only different urls, Outlook Version 2009 - newer because in preview channel) but not in another (Outlook Version 1908 semi annual channel). Addin is activated and loading in the web client but not in Windows Client.

Manifest (changed names, urls and guid)

What could be the problem? How can I troubleshoot what is happening? The obvious troubleshooting articles from microsoft did not help.

Edit: OnPremise Exchange 2016, Addin worked with other versions of outlook on windows (non 365 Versions)

outlook-addinoutlook-web-addins
A few things to check, do you know if this manifest works for other tenants on Outlook Version 1908? Do other addins work for this tenant? Is the 'Get Add-ins' button available? (Last 2 may point to addins being blocked by privacy settings) Is this tenant deployed through centralized deployment or installed by individual users? - Outlook Add-ins Team - MSFT
forgot to mention: this is an exchange 2016 onpremise server with outlook 365 clients (centralized deployment). Get Add-Ins button is grayed out. What do you mean by privacy settings and why should this differ from the web client? The addin worked before in this environment, but with non O365 versions of Outlook - roqz
I missed the link to the privacy settings. More info here docs.microsoft.com/en-us/deployoffice/privacy/… and support.microsoft.com/en-us/office/… Office clients can configure this independently from the web client. To confirm if this is related, try enabling Optional Connected Services. It would also be useful to know if other addins work in Outlook for this tenant. - Outlook Add-ins Team - MSFT

Thanks to the hints that Outlook Add-ins Team - MSFT gave I found the solution to my problem:

It was indeed the privacy control setting in the registry that has been distributed by group policies. In our case especially the key

HKEY_CURRENT_USER\Software\Policies\Microsoft\office\16.0\common\privacy -> controllerconnectedservicesenabled

was set to dword:00000002 (which is disabled).

After I changed it to dword:00000001 (enabled) the Add-in immediately appeared!

The relevant information can be found at the bottom of this microsoft article https://docs.microsoft.com/en-us/deployoffice/privacy/manage-privacy-controls
