SUMMARY
When you install the Microsoft Mail Connector onto a Microsoft Exchange Server, it will create a compatible Microsoft Mail for PC Networks PostOffice database. The Serial Number for this PostOffice will be 22- 28798.



MORE INFORMATION
If you attempt to connect two Microsoft Exchange Servers, using the Microsoft Mail Connector as your backbone, you will get the following error in the Event Viewer when starting the PC MTA Service:

The Microsoft PC MTA service returned service specific error 3

The Event log will contain the following entries:

Event ID: 4188

Source : Microsoft PC MTA

Type : Error

Category: Session

Description:

The postoffice NET/PO on \\computername\sharename and the postoffice NET1/PO1 on \\computername1\sharename1 have the same postoffice serial number [22-28798].

Make sure you do not have two drives pointing to the same postoffice.

Where NET/PO is one Microsoft Exchange Server, NET1/PO1 is another Microsoft Exchange Server, and \\computername\sharename is the MAILDAT$ share for the Microsoft Exchange Server PC Mail database.

Microsoft does not recommend using the Microsoft Mail Connector as a backbone for Microsoft Exchange Servers. Setting up the Microsoft Mail Connector is discussed in more detail in the Microsoft Exchange Server Administrator's Guide, Chapter 9.
