After you apply and enable the hotfix that is described in the Microsoft Knowledge Base article 823719, if your MAPI program calls the ResolveName function to connect to and use the MAPI address book provider, the ResolveName function call returns the MAPI_E_NOT_FOUND error code instead of the expected MAPI_E_END_OF_SESSION error code.
This symptom occurs when all the following conditions are true:
Your MAPI program connects to a Microsoft Exchange 2000 Server mailbox store.
Your MAPI program runs on either the Exchange 2000 server or on a member server that has access to Exchange 2000 Server MAPI components.
Global catalog referral is enabled on the Exchange 2000 server.
You have installed and enabled the hotfix that is described in the following Microsoft Knowledge Base article:
823719 Exchange 2000 MAPI address book provider cannot connect to a different global catalog server if the current global catalog server is unavailable
Your MAPI program calls the ResolveName function using the LPADRBOOK object that is retrieved by a call to the IMAPISession::OpenAddressBook method.
The global catalog server that your MAPI program points to becomes unavailable.
When all these conditions are true, the ResolveName function returns the MAPI_E_NOT_FOUND error code instead of the MAPI_E_END_OF_SESSION error code.
This problem occurs because MAPI returns the MAPI_E_NOT_FOUND error code even though MAPI receives an error from the MAPI address book provider when it tries to resolve names using the unavailable global catalog server.
To resolve this problem, obtain the August 2004 Exchange 2000 Server Post-Service Pack 3 update rollup.
