MAPI source connectivity

MAPI is one of the available methods of connecting to a source Exchange server. You need to choose the MAPI protocol if you connect to Exchange 2003, 2007 or 2010 without SP1.


The program currently allows creating only one connection to a source Exchange environment via MAPI. You can create multiple connections via EWS.

This section describes the most common problems associated with MAPI connection, with appropriate solutions. Use the links below to learn more.
