Envelope icon when using rules in Outlook

[whatever61]

That's an oldie.. and I didn't manage to find a solution all over the web over years, but never opened a thread for it.

When e-mail is arriving not to the Inbox folder (automatically moved to another folder, by applied rules), the envelope notification icon doesn't appear in the taskbar.
I tried the application MailAlert, which supposed to fix the problem, unfortunately it's not compatible with Outlook 2010 64bit.

I am aware of the desktop alert option, but I'm specifically interested in the envelope notification icon.
