Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
The 'good' news is, I finally have the most recent version. The 'bad' news is, when clicking "Update Now", it still produces the same popup, with the same 30088-27 error message.
Took your lead and got rid of OneDrive (now that I'm sure the error exists with or without it). I have ZERO use for that "service".
BTW, did you just uninstall it or did you do something else? I just uninstall it from Apps.
