MAPI LOGIN FAILED

my application is running as a service but I get MAPI LOGIN FAILED when I try to start a mapi session .It doesn't happen when running the application normally. Any ideas???

Sorry, I couldn't help you on this, but try putting username and password in. And also, force it to prompt for login screen.

And, perhaps, you could help me this:

I am writing an email/fax application using the VB MAPI control. And the code is basically like this:

MAPISession.SignOn
MAPISession.NewSession = True

MAPIMessages.SessionID = MAPISession.SessionID

MAPIMessages.Compose
MAPIMessages.MsgIndex = -1
MAPIMessages.RecipAddress = "[email protected]"
MAPIMessages.MsgSubject = "xxxxx"

MAPIMessages.AttachmentIndex = 0
MAPIMessages.AttachmentType = mapData
MAPIMessages.AttachmentPathName = "c:/test.txt"

MAPIMessages.Send

I have both Microsoft Outlook and Outlook Express on my machine. Everything looked pretty good as I was able to get my application to work with Outlook Express, but it fails when using Microsoft Outlook.

The error occurs on the line:
MAPIMessages.Send
and I get the following message:
"Unspecified Error Occurred 32002"

Is there any known problems using the MAPI control with Microsoft Outlook? Any information on this??

Thanks in advance.
