Mapi Fails on MapiSession.Outbox.Messages.Add

P: n/a
I am wirting an application in Access 2002 (XP) that needs to send email.
Since I hate the dialog boxes you get from all the Outlook warning messages,
I am trying to use the MAPI object. On *SOME* PC's the code runs fine, but
on others, the code can execute the logon portion of the code just fine, but
when it tries to create a message, I get the following error codes:

-2147221219, which when I look it up is MAPI_E_FAILONEPROVIDER. I can not
determine what the issue is.

The PCs have mixed OSs ranging from 98 to XP and various Access environment
ranging from none to XP. (I distribute code using Office Developer XP) I
have tested on my XP machine with Access XP installed and it works fine. I
have not found a pattern to the other PCs that don't work.

My code is below with the problem line marked with a '==>' in the l;eft
margin. The gstrMailProfile is a global variable that stores a profile
name. I have tested this by logging in without any profgile and having the
user pick a profile from the Outlook box.

I don't know what the error denotes or what the cause may be. Any
suggestion would be most helpfull! Thanks in advance.
