SUMMARY
When you attempt to modify a Microsoft Mail postoffice connection from the Microsoft Exchange Server Administrator program (Admin.exe), you may receive the following stop error message:

The postoffice NETWORK/PO could not be modified because either the MS Mail Connector server is unavailable or there is insufficient memory available to perform this operation.



MORE INFORMATION
The registry entry for the postoffice is missing. Restore the registry key from backup or manually restore the registry value for the postoffice in question using the Registry Editor.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.  Start Registry Editor (Regedt32.exe).  Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

     SYSTEM/CurrentControlSet/Services/MSExchangeMSMI/Parameters/Admin  Select this key to highlight it, click Edit, and click Add Value.  Create the registry value with the following parameters:

     Value Name: NETWORK/PO Data Type: REG_SZ String: \\Machine_name\Share /Z 

NOTE: For "NETWORK/PO" use the Network and Postoffice name for the postoffice in question. This data will be displayed in the Microsoft Mail Connector properties' Connections tab. For the String data, the example above is for Windows NT Server and LanManager compatible networks. For NetWare networks the path would be in the following format:

  \\Server_name\Volume\Path_to_Maildata For more information on configuring the Microsoft Mail Connector for Microsoft Exchange Server refer to the Microsoft Exchange Server Administrator's Guide, Chapter 14. This information is also available on Books Online included with Microsoft Exchange Server.
