Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
After trying everything listed on this thread, EXCEPT updating to the latest version and build using elevated command, I decided to once again do an online repair. After it completed I verified I now have 2407 (17830.20138) for Office. I tried the update now, and believe it or not, I didn't get the 30088-27 error, I got the message you are up to date!!!!!
I'm running Office 2021 Pro Retail 64-bit version, on my Windows 11 Desktop.
Just thought I'd share my latest to this confusing mess. Don't know if this is permanent, as I just finished the repair about an hour ago, but I clicked on update now several times and keep getting I'm up to date, NOT 30088-27.
Regards everyone,
Gordon
Forgot to mention. At the time of online repair I left the "Experiences that download online content" and "All connected experiences" turned ON. Not sure if the repair would have had the same effect if I had them turned off.
