Status Isn’t Open
At the MTA agent console, the Configuration Status box displays
the connection status as something other than Open.
If the configuration status is Closed, the MTA cannot access
the database in the domain or post office. Make sure the server
where the closed location resides is not down. Make sure the MTA
can access the server.
Verify the settings of the /dn or /user and /password startup
switches for the server where the closed location resides.
Verify the UNC path or drive mapping
to the closed location.
If the connection status is Open Pending, post offices in
the domain are in the process of opening and the MTA is clearing
its holding queues. After this is accomplished, the MTA begins processing
current messages and the status changes to Open. No action is necessary.
