That might not be the best advice until you understand whether they have a Microsoft 365 subscription or the single-purchase Office 2019 for Mac. The Mac App Store applications are strictly subscription versions and would overwrite the single-purchase license applications, causing license mayhem.

I would check Office for Mac and verify you are running the most up-to-date version. If you are please do the following:
