[OSX-Users] accessing exchange3 mail from Mail.app?

[Thanassis Tiropanis]

I have been happily using Mail.app to access my mail account on exchange3 but for some reason this seems to have stopped working  (I get back an authentication error), although I can access excange3 via entourage or Web (owa) with the same credentials.

So, I was just wondering, is anyone currently using Mail.app to access exchange3 mail successfully?

Many thx in advance for any responses.

cheers
