Redemption.dll库中的MAPI_E_NOT_FOUND错误

Question

I'm using Redemption.dll ( http://www.dimastr.com/redemption/home.htm ) in a project. The application uses MAPI to send emails for some testings. If the application is running on a machine that has outlook installed, it works fine.

However, if the outlook is not installed, I get this error when sending emails:

Error in IMsgServiceAdmin::CreateMsgService: MAPI_E_NOT_FOUND

After some search, I installed CDO 1.2.1 ( https://www.microsoft.com/en-us/download/details.aspx?id=1004 ) on the machine, but still get the same error.

Does it mean that the outlook has to be installed on this machine? Or, has to figure out a way to create a MAPI profile on this machine wothout installing outlook?

Thanks

Are you connecting to an Exchange mailbox or opening a PST file? Make sure there is only once instance of mapisvc.inf on your machine that lists the right MPAI services.
