Support for Office for Mac 2011 ended on October 10, 2017. All of your Office for Mac 2011 apps will continue to function. However, you could expose yourself to serious and potentially harmful security risks. Upgrade to a newer version of Office so you can stay up to date with all the latest features, patches, and security updates. Troubleshoot activation errors. If Office can't activate, it eventually becomes unlicensed and all editing features of Office are disabled. Office can become unlicensed for a number of reasons. For example, if your Office 365 subscription expires, you must renew your subscription to restore all features of Office.

If you've signed in to your Mac using a Network account such as Open directory accounts, this error may occur because Office for Mac can't write your credentials into the keychain as it is 'read-only.'

1. If you are signed in with a network account, sign out and sign back in with your local user account. Try activation again.

2. If you don't have a local user account, you must create one:

   1. From the Apple menu, select System Preferences > Users & Groups.

   2. Select Click the lock to make changes, and type your password. Select Unlock.

   3. Select +, and then fill in the new account information, and then select Create User.

   4. Log into your local user account and activate again.
