I have already discussed the problem with support. He recommended the forum to me. I can't get add-ins in Outlook 2021 for Mac because the corresponding button is grey.
I have tried all privacy settings. Connected experience is enabled. Reinstalling did not help either. Neither did the Outlook app from the app store.
I then tried creating a new profile. That doesn't work either. Although the old profile is deleted, the mails are still displayed.
If this is the case, the new profile we created should be loaded, not the old one. If it doesn't load the new profile we've created, it could be a problem with your Mac user itself.
As of the legacy version, Privacy, New Profile, and Reinstall Microsoft Office 2021 don't work to enable the Get Add-ins button in your Outlook for Mac. I recommend you post this issue to our Outlook community hub using this link: https://techcommunity.microsoft.com/t5/outlook/ct-p/Outlook Our Outlook tech community support is experienced in troubleshooting Outlook UI issues. They will respond within 24 hours, subject to availability. In addition, I recommend that you contact Apple support and ask them to help you create a new Mac user profile on your device. Once created, reinstall your Microsoft Office 2021 and see if it fixes the issue.
