Unable to activate office
UPDATE: For any interested parties, I was able to resolve this by disabling Modern Authentication for this user. Once the login interface changed and the user got the password prompt, they were able to activate office. I'm not sure how this will affect the the other user with this problem who has MFA enabled. I hope this will not start to become a widespread issue.

sbuntun after involving more resources, it seems that there is no such a known issue currently. It may be an issue in your environment. For further troubleshooting, could you provide the Office version number, the Office Channel and the version number of the Windows 10 operating system here?
