Have after updating MAC OS 27 been unable to save Word Docs onto One Drive or to my Save

This error on Word for Mac can occur even when storage is available because Word creates a temporary file during save or AutoSave, and if something in that process is interrupted, saving can fail with a disk space or memory message.

Try these steps in order:

1. Update Office for Mac
   • Open Word.
   • Select Help > Check for Updates.
   • Turn on automatic updates if available, then install all available updates.
   • Test saving again.
2. Try saving locally first
   • In Word, use File > Save As and save to a local folder such as Documents or Desktop.
   • If local save works but OneDrive does not, the issue is likely related to OneDrive sign-in, sync, or macOS access to the OneDrive location.
3. Check OneDrive sign-in and re-link it if needed
   • Open OneDrive from Spotlight.
   • Sign in again and, when prompted that the folder already exists, select Use this folder.
   • Let OneDrive resync, then test saving from Word to OneDrive again.
4. Check macOS privacy access for OneDrive
   • Go to System Preferences > Security & Privacy Preferences > Privacy.
   • Make sure OneDrive has Full Disk Access.
   • This is specifically required for Desktop and Documents folder backup scenarios on macOS.
5. If the file is in OneDrive Files On-Demand, make it local temporarily
   • In Finder, if the file shows as online-only, open it so it downloads locally first.
   • Online-only files cannot be opened without internet access.
   • Then try saving again.
6. Save frequently and test with a new document
   • Create a new Word document and try saving it both locally and to OneDrive.
   • If only one document fails, the problem may be specific to that file.

If the problem started right after the macOS update, the most relevant supported fixes are updating Office, re-linking OneDrive, and checking macOS permissions.
