XADM: PR_MESSAGE_FLAGS MSGFLAG_UNMODIFIED Bit Not Set Correctly |
The information in this article applies to:
-
Microsoft Exchange Server, version 5.5
SYMPTOMS
A MAPI transport provider explicitly sets the MSGFLAG_UNMODIFIED bit for
the PR_MESSAGE_FLAGS property of a new message during the call to the
IXPLOGON::StartMessage() method, and the bit is not set on the message when
delivery is set to the Exchange Server information store. If default
delivery is changed to a personal folder (PST) file, the new message will
have the MSGFLAG_UNMODIFIED bit set.
CAUSE
The Exchange Server information store was explicitly setting the
MSGFLAG_UNMODIFIED bit for the PR_MESSAGE_FLAGS property only in the case
where the information store delivered the message. When a transport
provider is "receiving" new messages, messages are essentially created in
the Inbox, not delivered.
WORKAROUND
To work around this problem, set default delivery for the messaging client
to a personal folder.
STATUS
Microsoft has confirmed this to be a problem in Exchange Server version
5.5. This problem has been corrected in the latest U.S. Service Pack for
Microsoft Exchange Server version 5.5. For information on obtaining the
