XCLN: Microsoft Exchange MS-DOS Client Fails with Memory Error

• Microsoft Exchange MS-DOS client, versions 4.0 and 5.0

SYMPTOMS

You can read messages in the Microsoft Exchange MS-DOS Client, but when you attempt to send, forward, or reply, the following error message might be displayed:

   The message could not be sent.

   You need more memory to perform this operation.
   Close some windows and try again.

   Microsoft Exchange for MS-DOS

   ID No: 5803 - 5001

CAUSE

This message can occur when the Microsoft Exchange Server fails to return required addressing information. In a very large organization with many address types, the address type information can exceed the RPC buffer space. The failure is returned to the Exchange MS-DOS Client as a lack of memory and results in the message shown above.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft Exchange MS-DOS client, versions 4.0 and 5.0

A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.

MORE INFORMATION

The corrected MS-DOS Client has a larger RPC buffer and is able to retrieve all of the information needed to complete the send, forward, or reply.
