    Hi

    I had the same issue and nothing I did seemed to fix it.

    However, I eventually and rather reluctantly downloaded and ran the Microsoft Support and Recovery Assistant and this fixed the problem :)

    Hi everyone.

    I updated my Microsoft 365 license key this week. It's now 6/26/2024. Microsoft still hasn't provided a solution to the problem (I haven't been able to find one yet). I can't use the 365 applications on my computer.

    Unfortunately, in my country, Microsoft seems to have hidden from customers, i.e. there is no way to talk to support, with a PERSON.

    We are instructed by the answering machine to download an application that is supposed to fix the problem. Sad mistake.

    But I haven't given up the search for a solution here in the community. And I found it in **** this question,](https://answers.microsoft.com/en-us/msoffice/forum/all/error-code-29-when-starting-o365/4b8bc600-affc-492d-aef9-f15b7c994e73?page=1 "answers.microsoft.com") opened by **** [CEtodayon June 15, 2024. The answer was given by William.Y - MSFT.

    I hope it will be useful to everyone who is facing this problem.

    And, I call on Microsoft to work on a solution to this problem, apparently very simple, so that we no longer encounter this small error that greatly inconveniences us.

    Microsoft, we believe in you!

    what if you don't have a key when you purchased it though the MS Store?

    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!

    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!
