SYMPTOMS
When you recalculate routing using the Microsoft Exchange Administrator program, the routing table may not reflect changes made to the routing in other Microsoft Exchange Sites.



CAUSE
In large topologies, these routes are not being removed quickly enough. Therefore, modifications have been made to the routing calculation to strip these routes more quickly.



WORKAROUND
Within a Site, one Microsoft Exchange Server is responsible for recalculating the routing information for that Site. This Exchange Server can be determined by clicking the General tab of the Site Addressing object you opened above and checking the Routing Calculation Server value. This Exchange Server must be running version 4.0.996.42 of the Microsoft Exchange Message Transfer Agent (MTA) or above.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server, version 4.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 4.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

S E R V P A C K



MORE INFORMATION
For example, an address space is deleted on a connector in Site 1 but the routing table in Site 2 still shows the deleted route. This deleted route still shows in the routing table even after a number of successful directory replication cycle have been completed amongst all Sites, even though the route no longer shows in Site 2's replica of Site 1.

The current routing table can be examined following these steps:


 * 1) Start the Microsoft Exchange Administrator program.
 * 2) Expand the Organization container.
 * 3) Expand the Site container.
 * 4) Expand the Configuration container.
 * 5) Click the Site Addressing object.
 * 6) Click the Routing tab.
