Thank you for your post.
FileMaker Pro will only send messages through MAPI compliant mail programs. I know that Thunderbird is not MAPI compliant, so that will not work.
I don't know why FileMaker Pro 10 is having trouble with Microsoft Live Mail. Has anybody else used Microsoft Live Mail successfully with FileMaker Pro 10?
Have you tried Outlook?
Microsoft Live Mail sounds like Microsoft's free web page based email account (also called Hot mail). If that's what we're talking about here then the answer is fairly obvious. This is a web browser controlled email account so there is no email server for filemaker to interface with.
Windows Live mail is Microsofts replacement for Outlook express, it is not web based.
The reason cannot be that Thunderbird is not MAPI compliant, because under Vista there is no problem with Thunderbird 3.......
No I haven't tried Outlook, we have no licence.............
