   When I want to synchronize Allocatus with Project, I get the following error:

   Mailbox unavailable.

   The server response was: 5.7.1 Unable to relay

   What can I do?

   The configured SMTP Server has to allow relaying to the Project Server IP-address. Ask your Exchange Administrator to allow relaying.
