A family of Microsoft word processing software products for creating web, email, and print documents.
This usually happens for one of these reasons:
- The file is stored in OneDrive or SharePoint, and the signed-in Microsoft 365 account does not have permission to upload or save it.
- In Word, open File > Account.
- Check which account is signed in under User Information.
- If the wrong account is signed in, select Switch Account and sign in with the account that owns the file or has access to the OneDrive location.
- The file location is read-only or the current account only has read access.
- If the document is in a shared OneDrive or SharePoint library, upload requires edit permission.
- If permissions were changed, access to upload can be removed even if uploads worked before.
- In that case, the file owner or administrator must grant edit permission.
- The document has restricted permissions applied.
- Some Word files are protected with Information Rights Management (IRM).
- If that is the case, actions such as editing, copying, printing, or forwarding can be blocked.
- In Word, open the file and look for a message bar about permissions, then select View Permission or View Permissions to see what is allowed.
- If upload or sharing is restricted, the file owner must grant less restrictive permissions.
- As a workaround, send the file without uploading it to OneDrive.
- In Word, go to File > Share.
- Choose Attach a copy instead to attach the document directly, or choose Upload to OneDrive only if the signed-in account has permission.
If the problem only happens with one specific document, restricted permissions on that file are the most likely cause. If it happens with all Word documents, the signed-in account in Word is the first thing to check.
