SUMMARY
This article explains how the Microsoft X.400 Connector handles high-priority mail (including delivery and non-delivery reports).



MORE INFORMATION
The Microsoft X.400 Connector will open a new X.400 association with the partner X.400 message transfer agent (MTA) when a high-priority message, delivery, or non-delivery report is queued for the partner X.400 MTA. (Delivery and non-delivery reports do not have priority indicators. Following X.411 spec, they are treated as high priority.)

The new X.400 association will be used only for high-priority messages (including delivery and non-delivery reports). Normal or low-priority messages will flow across the existing association or a new association will be created.

Note that high-priority messages can cause the establishment of a second association even when the number of queued messages has not reached the threshold value configured on the Override tab of the Microsoft X.400 Connector Property page.
