Hi,
Thank you for posting in Microsoft Q&A forum.
Per my experience, you are failed to use Microsoft AutoUpdate to deploy Word update for your Mac clients. If I have misunderstood anything, please feel free to let me know. How many clients are facing this issue?
Can we manually update Word app using the update file on Microsoft's website:
Release history for Office for Mac

Thanks for your time. Have a nice day!
Best regards,
Simon
