Exchange 2007 Transport Service keeps stopping

Email was down because the mail database needed to be mounted. Mount the database and then start the transport services. It started after a while but then would stop within seconds.

  1. Navigate to C:\Program Files\Microsoft\Exchange Server\TransportRoles\data\
  2. Change the folder “Queue” to something else, such as “Queue.old”.
  3. Start the transport service. It may do this automatically and make the folder by itself. Within a few minutes mail should start flowing.
