Hi Sergey,

It should be something like that. So after that I installed Microsoft Office 2010 beta. At least the
message changed. Now it says "An email client doesn't exist by default, or the one used can't satisfy the email requirement. Execute Microsoft Outlook and define the program as the email client by default"

In File, Options, General I clicked on define Outlook as the program by default for email, contacts and calendar. Still I receive the warning message when I launch my application.

>It sounds like MAPI is not configured correctly on the PC. Did installing Mozilla Thunderbird fixed the problem?
