Consider the following scenario:
  • You enable the Exchange store tracing feature for the tagMtgMessageChange or tagCalendarChange tags on a Microsoft Exchange Server 2007 mailbox server.
  • You access a mailbox by using a MAPI application.
  • The application sets properties on a message by using the SetProps method, and then it calls the SaveChanges method to commit the change.
  • The MAPI application calls the GetProps method to obtain a sender’s properties. For example, the application calls the PR_SENDER_ENTRYID property.
In this scenario, the MAPI application cannot obtain the property. Additionally, you receive the following error message:


This issue occurs because the GetProps method accesses an invalid object that is not initialized correctly when the Exchange store tracing feature is enabled.
