Currently have a LYNC 2010 environment w/ Exchange 2010 and Exchange 2013 co-existing. When I look at the Configuration Information for LYNC, under "MAPI information",\
Exchange 2010 user has "MAPI Status OK " for BOTH Value and Status
but
Exchnage 2013 user has "MAPI Status OK" for Value, BUT for Status has "MAPI not installed"
Not sure if this is expected behavior, or something I did wrong, any suggestions? thanks all
