how to fix error 29 in office 365

Could kiss you, and I don't even know you.

Thank you. Worked with one restart. Why could MS people not come up with this?

Hello PeanutKimKim,

Thank you very much for the instruction above. I was trying to fix this since several weeks, on and off. I followed your instructions. One thing was different for me, I had deinstalled the office software, because I did not trust all the MS instructions any more I reinstalled office after downloading the software for local installation without internet. However your instruction are clear much better then the MS ones above and within the maze of KBs.
Thanks again.

Hi Can this be used INSTEAD of the fix at top of page from MS person?

I've got this problem since I signed out from Outlook the other day only intending this to be temporary. That revealed what I now understand to be this bug with error code 29 and MS 365 will not activate. This is really disurptive not being able to use Outlook for email comms is impacting my work.

I have tried the script mentioned above but from this thread which seems to be basically the same. It was run with admin priveleges.

But the script fails. Below is a copy of the scripts I ran as I tried to follow. Initially I seemed to have to take the % signed out and that seemed to get me further but then failed again.

If there is no sign of a fix any time soon then I really need some help to see if I can downgrade to the last stable version.

I shoudl metnion in case it might affect the runnign of that script that all my files are stored on a different partition to C including the outlook pst files. Would that cause the script to fail? On the face of it, it seems to only be referencing C:

Can just use PeanutKimsKim's fix on its own?
