If you use Exchange 2000 event sinks, and the Uniform Resource Locator (URL) of an incoming message is passed to the OnSaveSync event, that URL may be incorrect. This problem occurs if:
  • The message subject is the same as the subject of an existing message in the same folder.
  • The message was modified by a virus scanning applicationprogramming interface (API) version 2.0 virus scanner after the message was committed to the store.
The first time that the event sink starts, the URL is correct. However, the second time that the event sink starts (after the virus scanning API modifies the message), the URL is not correct. For example, if the correct URL is http://.../inbox/message-4.html, the incorrect URL http://.../inbox/message.html is passed.
