Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
After spending laterally 4 hours on a chat with customer support, 2 agents were not able to solve this issue with me. The agent was at a point where he suggested to reinstall windows to solve the issue.
I did a fresh install of windows and even then. Every time I open a 365 app, it prompts me for a login (even though I am already logged in) and then it gives me the error message code 29.
I can have access to my apps, but it is still annoying.
