Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi
I split your reply off because that thread has gone stale. It's from months ago and so many people jumped in with different stuff I can't figure out who did what where and when.
First, please do a Safe Boot. Hold the SHIFT key down as your Mac restarts. Once your Mac boots up,
download, install and then run the latest version of AutoUpdate to update Office. Hopefully, the download will complete normally.

After install, do a regular restart.
