Oct 26, 2011 - Starting with Exchange 2007, neither the Messaging API (MAPI) client libraries nor CDO 1.2.1 are provided as a part of the base product.
Hi, Thanks for the reply. AdminUser is our domain Admin and i've just created a profile on a network PC and opened up the mailbox in outlook 2013 with no problem. I have also added the MailUser profile to AdminUsers's Outlook profile and been able to send a mail externally from that user. When you say open another account with AdminUser Credentials do you mean ANOtherUser in MFCMapi and the answer is NO When i run the EMS Commands with a ANOtherUser i get the MFCMapi Errors. Error: Could not add service to profile. Perhaps service is not in MAPISVC.INF?
