Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
So I kept geting this error, updates didnt work, repair online or quick also it came back.
I then went to reinstall office and noticed, I had 2 installs of my office 365 family subscription.
I had reinstalled windows on same machine. So maybe Msoft cant tell the difference as it uses processor id or somthing.
I deactivated the computer name I used before reinstall/rename and then clicked outlook, worked immediately no repair, nothing.
Guess you can check?
