A couple of thoughts:

You can simply leave off the version number and Windows will the default version of MSAPI on each client.

You may run into problems with a security feature of Outlook 2002 when sending mail from an anonymous client. Check this article http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaskdr/html/askgui04022002.asp

>The 1 in MSAPI.MAPISession.1 is the version number of the DLL. I don't know off the top of my head what the version of MSAPI is installed with Outlook 2002, but that is probably the source of your problem.

>>I am using the mapimail class to send email from a VFP 6.0 app. Everything works fine for Outlook versions prior to Outlook XP/2002. Users with Outlook 2002 are running into a problem with the following line of code in the mapimail class:
>>
>>** Create a session object
>>loSession=CREATEOBJECT("MSMAPI.MAPISession.1")
>>
>>It is not creating the object...any ideas?
