Set up work email on your Android device

The email client on Android devices can vary greatly, some use the Gmail app for all email whilst others (such as Samsung, LG etc) have a separate email app (often called "email" or "mail"). Regardless the principle to set up is the same.

Open the relevant email apps settings and add an email account
At this stage make sure you select the account to be an "exchange" account, IMAP/Pop etc will not work
The various email apps will ask you for information in different orders but the details you will need are as follows:

Email address - your full email address
User name - your network user name (usually firstname.surname)
Password - your usual network password
Domain - Santok
Domain\UserName - Santok\firstname.surname
Mailserver - mail.santok.com 

And that should be all you need to set it up.
