I coded a transport provider based on MAPI protocol. My transport provider only takes responsiblity for a message class that is specific to my messages (ipm.note.vmail)



When my transport provider is added to a profile, deferred delivery no longer works for Outlook 2003. The messge just sits in the Outbox until the user manually hits send/receive (after the delivery time). Deferred delivery works great if I remove my tp.

Any suggestions?
