A family of Microsoft word processing software products for creating web, email, and print documents.
Hello David K,
Thank you for reaching out in Microsoft Q&A forum.
I understand how frustrating this is, especially since Word was working normally before and suddenly you can’t create or edit documents.
On Mac, this usually happens when something around permissions, file state, or licensing changes in the background (for example after a macOS update, a Word update, or a licensing refresh). With Office Home & Business 2021, Word should always allow editing once the license is recognized.
You can try these steps:
- Confirm the document is not read‑only or locked
- Open the file in Finder > Get Info > make sure Locked is unchecked and you has Read & Write access. Read‑only files will open but cannot be edited.
- Check Word’s license status
- Open Word > Word menu > About Word.
- Confirm it shows Office Home & Business 2021 as activated. If Word temporarily loses the local license file, editing is disabled even though it worked before.
- Sign out of Word and sign back in
- Word > Sign Out, then restart Word and sign back in with the account used to activate Office 2021.
- Allow Office background components
- macOS Settings > General > Login Items & Extensions > allow Microsoft Office / Microsoft Corporation items to run in the background.
If none of the above restores editing, reinstalling Office: Download and install or reinstall Office 2021, Office 2019, or Office 2016
Hope this helps
