MAPI error

[David Schwartz]

If there isn't a decent alternative for the MAPI Session control in VB.NET,
I'm content to stick with the ActiveX control, however I get an error in the
following code:

With MapSessOCX
.DownLoadMail = False
.LogonUI = True
.SignOn()
.NewSession = True
MapMess.SessionID = .SessionID
End With


The error is "Application-defined or object-defined error" and it occurs
when I call .SignOn().

Any ideas what may cause this and how I can fix it (or workaround it)?

Thank you very much!
