MAPI Failure 64bit OS, 64bit Office, 32bit Application RRS feed

  • Question

  • Hello all,

    I've been developing an application that calls on the mail clients to send the current document out. On a 32bit OS, with a 32bit Office it sends just fine. 64bit OS, 32bit Office, it again works just fine. When I get to 64bit OS on 64bit Office, the application throws a MAPI failure of an unknown origin.

    I have tried to remap the MAPI with registry keys and that hasn't worked. Does anyone have an answer for this?
