We edited the group policy on users machines to delete the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\AuthRoot\Certificates key which has resolved the problem.
Delete the following registry key manually:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\AuthRoot\Certificates

To do this, follow these steps:

1. Start Registry Editor
2. Locate the following registry subkey:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\AuthRoot
3. Right-click and then delete the key that is called "Certificates"
4. Open Outlook - problem sorted!
