The server name you need to use (For Exchange/ActiveSync) is m.outlook.com. If you experience difficulties using m.outlook.com, you can also try pod51000.outlook.com. If setting up by POP3 or IMAP, you must use pod51000.outlook.com.
Your username is always your entire CUW email address (not your Student ID)
If it is not accepting your password, it may be because your password has not been synced up correctly between CUW's servers and Microsoft's servers. You can resync your password simply by "resetting" your password at getstarted.cuw.edu. (You can "reset" your password to the same thing if you like)
If you experience any difficulty in setting up your mobile phone for your CUW email, the IT Help Desk can assist you. They can be reached at x4357, by email at firstname.lastname@example.org, or you can submit a request for assistance online at helpspot.cuw.edu.
