Hi Sergey,

Is it possible that I can scan all the application in the Windows and if I can find the window caption "Inbox - Microsoft Office", I will set focus to that window.

I was thinking that Outlook 2000, Outlook 2002 or Outlook 2003 might have different caption in their Inbox foder. They might include the Outlook version in the windows caption such as
"Inbox - Microsoft Office Outlook 2003" for 2003,
"Inbox - Microsoft Office Outlook 2002" for 2002, and
"Inbox - Microsoft Office Outlook 2000" for 2000
