Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Appears to be a known error... Error code 29 when starting O365 - Microsoft Community
Experiencing the exact same issue with Office 365 and Copilot Pro.
Fighting with it for days only to be advised by Level 2 this morning after pushing issue... Dang
* Looks like removing Copilot will create more problems after reading this post. Cheers all
