SYMPTOMS
When Collaboration Data Objects (CDO) are run from a service by using the account of a user who is not logged on, an attempt to pass a distinguished name (DN) to the profileinfo string of the logon call may fail and a MAPI_E_NOT_FOUND error may occur.



CAUSE
This problem can occur if MAPI.Session.Logon fails when it passes a profileinfo string that contains a DN with invalid file-system characters. Messaging Application Programming Interface (MAPI) does not create the MMP file for the profile because MAPI uses the profile name from CDO without checking for invalid file-system characters.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.
