Okay, so I recently upgraded my Hotmail.com account to use Outlook.com for e-mail (but retaining my hotmail.com address as my login for now). However, I'm trying to set up the account to use Microsoft Exchange but I'm having trouble. When I open the Mail, Contacts & Calendars system preferences pane I choose to add an exchange account with my hotmail.com address as e-mail and enter the correct password. The pane tries for a hotmail server but gives up and asks for more details. So I correct my username to be my full hotmail e-mail address, and I enter "m.outlook.com" as the exchange server which is what I believe it's supposed to be. However, the preference pane just complains that there was a problem and that I should check my login details. If I continue anyway then none of the accounts that it sets up work (as if my account details were wrong). I've tried using hotmail addresses for the exchange server but none of them seem to work (invalid address) so I expect they may have been shut down. Anyway, I've tried trawling through Microsoft's useless support documents; I couldn't even find one that gave details of exchange setup, only one mentioning it as the preferred method but going into no further detail whatsoever. I got the "m.outlook.com" address from user questions from a search; it seems like the right address and seems to be a valid server but it just won't accept my username and password. Has anyone else managed to set up an Outlook.com e-mail account as an Exchange account on OS X Lion (or Mountain Lion)?
