Dear RennieSchmid
Thank you for your response.
We have received feedback from other users who are experiencing similar issues to you, so we need to investigate if this is a bulk issue.
We are currently trying to find a solution, you can go to your account homepage, go to the "Privacy" option, find Microsoft 365, and turn all the options on or off, for example, if they were on, turn them off. Then wait for some time, reopen Office and check the situation.


If it still doesn't work, we suggest you uninstall Office manually and download the offline installation package to install it.
You need to go toyour account homepageand check the version of Office you have in the "Services & Subscriptions" screen. Click on "Install" and a window will appear. On the screen that appears, select "Version" as "Offline Installer", which will download a larger installation package of about 4.9GB.
Disconnect your computer from the network after the package is downloaded, open the package and select setup64.exe to install it.
I hope the above information has been helpful to you. Please feel free to reply if you need further assistance.
Best Regards,
Tracy | Microsoft Community Support Specialist
