Not sure if this helps but been a mobile me user for a year now and this is my outlook 2007 settings:
Also worth noting I have seen in small print that iCloud will only work with Outlook 2007 & 2010
Account type: imap
Incoming mail server: mail.me.com
Outgoing mail server: smtp.me.com
- (I note that Apple's KB of this states: smtp.mail.me.com i.e. mine does not have "mail" in it).
User name: (_ _ _ _ _)@me.com (don't put in @me.com though)
Tick require logon using SPA
on advanced tab:
outgoing server tab
my outgoing server (SMTP) requires authentication: tick this
use same settings as my incoming mail server: click this
Advanced tab
Incoming server (IMAP): 993
Use following type of encrypted connection: SSL
Outgoing server (SMTP): 587
Use following type of encrypted connection: TLS
So far my account is still working but have not upgraded to iOS5 or iCloud yet as waiting for update to another program that I use to bypass iTunes for music importing.

Wow...found an answer elsewhere. Basically, sign out of iCloud (System Preferences --> iCloud), restart, sign in to iCloud, restart, open Mail. Everything seemed to reset just fine, and I could save changes to the account in Mail Preferences.
