XFOR: Error Adding Connection to Microsoft Mail Connector (166147)



The information in this article applies to:

  • Microsoft Exchange Server 5.0
  • Microsoft Exchange Server 5.5

This article was previously published under Q166147

SYMPTOMS

When you create a direct connection to a Microsoft Mail postoffice using the Microsoft Exchange Server Microsoft Mail Connector, the following error message may be displayed:
A postoffice with the name already exists on the network. Enter a
different name.

CAUSE

There may be an erroneous postoffice definition in the Microsoft Exchange shadow postoffice.

RESOLUTION

To resolve this problem:

  1. Map a drive to the Exchange Server shadow postoffice. The shadow postoffice is shared on Exchange Server with the hidden sharename MAILDAT$.
  2. Run the Microsoft Mail Administrator program, Admin.exe, against the shadow postoffice and look at the External postoffice definitions. If there is an entry for the postoffice you are attempting to connect to, remove this entry.
You should now be able to add a connection for that postoffice in the Microsoft Mail connector.
