I get this message every time I start Word or Excel and enter my valid email account name:

Just a FYI, do NOT bother formating PC and attempting a clean install again. Same issue still persists.
Attempted on multiple PCs.
I have restarted.
I have reinstalled O365.
I have checked for and installed the latest Office updates.
I have changed my MS account password.
I have two other computers with O365 installed (wife/daughter) and neither has this issue.
MS just doesn't like me...
No use, I already tried it. Once you opt copilot, your license is already ruined.
Hello wanzhiyu,
I encounter exactly the same problem as you describe. Yesterday, I got online chat support by Microsoft on this issue. A level 2 support agent told me that this problem is indeed due to Copilot Pro and that it is known at Microsoft. The engineers are currently working on a solution and will provide a fix soon.
Best regards

I think I have identified the issue, but i am not sure. I reinstalled the system and logged in only with my personal account, without activating the work account, and I still encountered error 29. I then recalled that I had signed up for Copilot Pro today, which seems to have caused my license to not renew properly. However, I am not certain if your situation is the same as mine. And I do not know how to solve this problem.
