Set up SPN for Exchange server

Tip: You only need to perform this step if you are using Microsoft Outlook on-premises.

To enable the Outlook add-in to communicate with the FM portal, a Service Principal Name (SPN) must be configured for the Exchange server. If one does not yet exist, set it up as described in this article.

Procedure

1. Check whether the SPN already exists. It should point to the URL of the Exchange server. Use the following script:
   
   setspn -Q SPN

   Example:
   Exchange server domain = mail.etask.de
   SPN = http/mail.etask.de
   setspn -Q http/mail.etask.de
   
   

2. If no SPN exists for the Exchange URL, create the SPN. To do
   this, use the following script:

   setspn –A SPN HOSTNAME

   Example:
   Exchange server URL = mail.etask.de
   SPN = http/mail.etask.de
   setspn -A http/mail.etask.de
