Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Thank you. Fixed my problem which started when I changed my password on a different Microsoft email account (account #2) and also linked my cell phone number on that account with the same cell phone number that was already registered on my Microsoft 365 account (account #1). It didn't like this, suddenly linking my Microsoft 365 account to that other email account which does not have a paid version of Microsoft 365 attached to it. My apps (Excel / Word /etc) refused to acknowledge the paid version of Microsoft 365 despite showing that the apps successfully logged into that account. This program fix corrected the problem. Thank you again.
