Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Just reinstalling Office will not correct the issue unless it is the only device you have it installed on. You must sign out of any / all of your OneDrive accounts. You will have one for each Microsoft email address. You must do this on all devices. Once you have signed out of all your accounts on all of your systems (iPhone, iPad, Computers) you can then restart any office application, follow the privacy prompts, and that should "cure" your issue. There have been no "negative" responses to the instructions I've provided. All have found them to "cure" the issue.
