The event sink does not fire as expected on a computer that has both Exchange 2000 SP2 and ScanMail for Exchange version 6 installed

Consider the following scenario. You bind one of the following items to a folder that is located in a user's mailbox in Microsoft Exchange 2000 Server:

• An Exchange Mobility Event Sink
• Any store event sink

Then, you use a rule to move incoming messages to a specific folder. In this scenario, the event sink does not fire.

Note This problem occurs after you install Microsoft Exchange 2000 Server Service Pack 2 (SP2)

This problem occurs because of an issue that occurs when Exchange 2000 Server SP2 and Trend Micro ScanMail for Exchange version 6 are installed on the same computer.

For example, if you follow these steps in the order that they are presented, ScanMail for Exchange version 6 scans the message as expected:

• You install Exchange 2000 Server SP2.
• You set up an event sink on the store.
• You install ScanMail for Exchange version 6 on the Exchange 2000 Server SP2 server.

However, the event sink does not fire.
