You will first need to find your server settings for you email account. To do this, sign into your e-mail account using Outlook, our the School E-mail Website. After you sign in, click the drop-down arrow next to the Help question mark, and then click About. scroll down and find the External IMAP and SMTP settings area (about half way down the page). Copy this information down.
Next get your phone and go to Settings>Accounts>Email/Add Account (may be different for certain Android phones) when you go into these settings you will use the External IMAP info for the incoming server settings and the External SMTP info for the Outgoing Settings.
I hope this helps...you can also follow this link
