Why does Outlook 2011 for Mac keep giving me the error:

Outlook for Mac may give this error to users who are using an outdated software version.

  1. Go to Help in the top menu within Outlook.
  2. Click on "Check for Updates".

Outlook also may give this error if there is a corrupted keychain entry:

  4. Once you locate the Keychain file for Outlook, drag it to the trash bin.
