SUMMARY
In earlier versions of Microsoft Exchange Server, the Stack tab in the properties for an X.400 Connector contains a Use Expedited Data check box, regardless of the type of transport stack you are using. However, selecting the Use Expedited Data check box can increase communication speed only if you are using a Transport Class 4 (TP4) transport stack.

Therefore, in Exchange Server 5.5, the check box is not available if you are using a Transport Control Protocol/Internet Protocol (TCP/IP) or Transport Class 0 (TP0)/X.25 transport stack.



MORE INFORMATION
The Use Expedited Data check box is used to increase communication speed on networks that recognize data packets identified for accelerated transfer. Some networks require the use of expedited data.

Additional query words: message transfer agent mta transport stack
