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.

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.
