Had the same problem so I just used the setting from my Outlook Web App
Here's the way I did it for my X:
Go to Outlook Web App for your school and choose options.
Select account
At the bottom of the account page there should be a link that says Setting for POP 3... ect...
Click it.
It should open a window with all the Protocol Settings needed for your account.
Go to accounts on your phone and select a new account
Choose the manual config option.
In general settings fill in the correct info
For incoming server select IMAP server
Server name should match what your Protocol settings from the web app lists (ex. pod51000.outlook.com)
User name should be your full school email address
Password is your school email account pass
Select advanced settings and use the port from the protocol settings (ex Port 993)
check Use secure connection
Use secure pass = Always
check Verify Certificate
For outgoing server it should be the same as Incoming Server
Same thing for advanced setting with the outgoing SMTP port setting (ex 587)
Check secure
Use secure pass = never
Authentication = Auto
Check Verify Cert
Of course other settings is how many messages you want in you inbox. I chose 100
Don't know if this works for everyone and I am no IT genius... I just played around with it till I got it right.
Hope it works!
