This sounds like a situation that is best remedied by contacting the IT people at work. It may be a situation where they are blocking external e mail services on unauthorized devices.

Can’t Send Emails on iPad – Troubleshooting Steps
Setting up and troubleshooting Mail
Why Does My iPad Say "Cannot Connect to Server"?
Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.
