University email on my android

i want to add my univerisity email on my android app but is asking me for client certificate could you please help me how to fix it. 

When you are adding a new account to the email client, you only  need to put your full UoB email address and your normal password. If you are asked to install a certificate, then accept the default.

If you are encountering any other problems please call into to the IT popup in the Luton LRC on Monday between 11 and 1.
