Where’s the Exchange 2007 SMTP pickup directory?

Ryan IM’d me to ask where the Exchange SMTP pickup directory went in Exchange 2007. Good question; it did indeed move, as part of the overall move away from the IIS core services that Exchange 2000 and Exchange 2003 used. The Exchange 2007 pickup directory defaults to c:\program files\microsoft\exchange server\transportRoles\pickup. (Note the space in “Exchange Server” and the lack of one in “transportRoles”). Drop your message in there and away you go. You can also use the Set-TransportServer cmdlet to set some pickup-related parameters, including where the directory is and what size messages it can accept.
