I am unable to reactivate Word

Geoff Hodgson 20

I am using Mac OS12.7.6 I have a paid subscription to Microsoft 365. All my Word documants are now "view only" I have made several attempts (at least five) to reactivate Word but the protocols won't let me complete the sign-in process in order to reactivate Word

If your version of MacOS is Monterey (12.7.6), then the error you are seeing is caused by an update in July, many people are seeing the exact same error, if you are unable to upgrade your MacOS to a newer compatible version, your Office apps will go into Read Only mode or cannot be installed, on the link below the full details on that update are provided.

The last version of Office that will work on MacOS Monterey is 16.88, that is available on the long table on this link to all the downloadable versions from the Microsoft servers, if you have any previous version of Office installed on your Mac, that needs to be uninstalled first.

Thank you Dave, I am using Monterey and your recommendation to install Office 16.88 worked! I'm very grateful for your help with this.

Here's my article on how to download, install and activate Office on your older Mac: Most Recent Office You Can Run - Best Practices

It's not necessary to uninstall Office first, instead simply update to 16.88. After installing, run Help>Check for Updates in any Office product to get the final 16.89 that runs under Monterey.
