I just got through installing the Skype toolbar for Microsoft Outlook, and I’m impressed. (That’s not saying much; I’m impressed by pretty much everything Skype does.) The toolbar, among other things, associates an active email message with your Skype contacts so you can dial directly from Outlook. You can also initiative SkypeOut calls to any contact phone number within Outlook. The web page for this beta application lists a number of other features I haven’t yet tried, but so far, I’m thrilled. I can Skype a contact instantly after getting an email from him without having to switch apps. Very nice.
