Outlook notifier

Im just woundering if anyone uses notifiers for this app and if so which ones?

I personally would like to try one, but when I did a search most of them were not free unfortunately. Got any recommendations?
:D

Ive used True Launch Bar most of the time but was looking for other suggestions.

Here's a few notifiers.
I don't use them myself so i can't comment on how good they are.
