    I did the same spending several hours reinstalling MS365 and looking at my copilot pro account. She transferred me to another department and my issue was finally resolved in 15 minutes.

    Thank you for your reply. After a few different agents I was lucky enough to get connected to someone fantastic and shared a comment I found in this thread. She uninstalled the product and re-entered it and it was fixed in about 1 hour.

    I don't know if this is exactly what she did but she was straight into my computer once I shared it.

    Dear all,

    the Error 29 could be solved:

    1). open command prompt as Admin

    2). cd c:\Program Files\Microsoft Office\Office16\

    3). cscript ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX"

    Was being driven mad with this issue, saw this solution somewhere else, it worked flawlessly!

    https://learn.microsoft.com/en-us/office/troubleshoot/activation/reset-office-365-proplus-activation-state#method2 Just run the automated scripts, then open word or some other office app and try to login. Worked for me at least!

    finally... this was driving me mad today, when I did logoff and logon again in Office. Then, I got this error. It seems, the credentials are not unloaded correctly.

    Now, I can logoff (not that I need to) run the scripts and ok.

    The whole mess started today when I did try out the Windows Pin, but then, reverted back to normal logon. Then, suddenly, Onenote said, it is not activated, etc.

    This is on you, Microsoft!
