Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Thank you for your responses Jess - I do appreciate it. I will try to answer your questions. The old docs were created in an older version of Office fro Mac. All of the docs were created by me, so it seems I should have permission. Frankly, I am not confident I have a clear understanding of some of the suggestion I have received... but one thing I notice is when I save a document to the iCloud Drive, it saves fine. Thank you.
