I'm talking about the alias email address. . .e.g. if you have a hotmail email address xyz@live.com you can create another alias for that but whenever you want to log in you've to use the original id and NOT THE ALIAS. Mails sent to the alias is shown in a separate folder.
Since I've never used Hotmail I wasn't aware of the Alias feature. Using Sparrow when you get your Hotmail using the main address are you also getting the messages for the Alias address?
Nope. It requires exchange support.
I don't believe that Sparrow supports Microsoft Exchange. Are you having the Alias email placed into a folder within Hotmail? If so, and you changed the Alias to leave it in the Hotmail Inbox, will Sparrow then retrieve it?
