Windows Live Mail issue - no sound or popup notification

[abanerji]

I have just started using a new Win7 laptop. In Windows Live Mail Version 2011 (15.4.3538.513), when a new mail is downloaded from the IMAP server, there is no sound or popup notification. I think that all necessary sound / notification settings are properly checked in Windows Live Mail > Mail > Options. My sound is ok. I even get a windows default sound, when some error is notified in Windows Live Mail.

I have been using OE (under XP) and WinMail (under Vista), and this problem does not happen there.

I searched in the internet, and find similar problem faced by other users.
