Drumroll: MAPI is now Outlook Exchange Transport Protocol

by Bharat Suneja

Messaging Application Programming Interface – or MAPI, the equally loved (overstatement?) and hated protocol used by Microsoft Outlook to communicate with Microsoft Exchange Server, just got rechristened! It’s now called Outlook Exchange Transport Protocol. Found this little tidbit burried in Paul Robichaux’ blog.

Saw it mentioned as such on a Microsoft licensing web page not too long ago (linked from Paul’s post), but I didn’t really hear or read about the name change till I saw his blog post. As he notes in the post, “MAPI is dead as a name, but I suspect it’ll be a loooong time before those four letters are expurgated from all of the existing MS documentation and support materials”… and from our collective memories, if I may add.
