Email is now working as normal.
The link at the bottom of the webpage; https://mail.office365.com will take you to the correct web page if you are using email externally. Enter your email and password as normal.
If you had email configured on an IOS device before, to reactivate it go to settings>Mail, Contacts, Calendars>Add Account>Exchange and enter your work email address and password here. If this was not configured before it will not work, you will need to see one of the IT technicians.
Apologies for any problems this may have caused you.
