If the problem still exists:

1. Restart IIS.
   In many cases this step will fix the problem. If not, continue with the following steps.
2. Open the MailMarshal Exchange Configurator.
3. Go to  Tools | Server Properties | Advanced and ensure the MailMarshal Exchange Stub is installed and active.
4. Restart the Exchange IIS Admin service (the other dependent services will automatically be restarted).
5. Go to Admin Tools | Services.
6. Restart the MailMarshal Exchange Controller service.
