A family of Microsoft word processing software products for creating web, email, and print documents.
Hi, Susan Warda
This usually points to a Mac permissions/cache problem or a Word/OneDrive sync issue, not necessarily a bad document.
Here are some suggestions you can try:
In Word, go to Word > Preferences > Save, turn on Save to Computer by default, and set a local folder on the Mac as the default save location. That can stop Word from bouncing between cloud and local locations.
In macOS, check Privacy & Security > Files and Folders for Word, and if needed also Full Disk Access, so Word can write to Documents/Desktop properly.
It is recommended that you clear the Office cache on the Mac if Save/Save As has started hanging or failing. That is specifically documented as a fix for Office save problems on Mac.
If the files are in OneDrive, it is suggested that you turn off "Use Office applications to sync Office files” in OneDrive settings, so Word saves locally first and OneDrive syncs afterward.
If the Save As window itself is glitching, try Command + Shift + S as a temporary workaround. This is a commonly effective bypass for broken Save As behavior on Mac.
Thank you for your patience in reading, I hope this information has been helpful to you.
