SYMPTOMS
When you connect Microsoft Exchange Server to other X.400 systems or to other Exchanger Servers computers via an X.400 connector, Exchange Server does not use a reliable transfer service element (RTSE) window size greater than 3. Exchange Server requests the window size is 3, even if the configuration in the MTA Override Property Page says 5 for example. If the connection is opened by another MTA, Exchange Server will negotiate the RTSE window size down to 3.
