how to fix error 29 in office 365

Anonymous

Cannot reactivate office 365 and get error code 29 when updating license. I've uninstalled and reinstalled all the programs, and followed all the online steps suggested by Microsoft. I've tried the Office 365 self-repair tool, and re-logged into my Microsoft account. Nothing works.

For a simpler fix, you can try these:

Close all Office apps first.

Go to File Explorer > View > Show > Hidden items.
Navigate to C:\Users\*your username*\AppData\Local\Microsoft
Delete IdentityCache folder
On the same page, look for OneAuth folder and open it.
Delete the contents of OneAuth folder such as "accounts" and "blobs"
Launch any Office apps and sign in your account. You might need to relaunch the app multiple times until the error is gone.

Let me know if it works for you!

Kind regards,
