Invalid certificate error on mobile phone

I have an Orange Rio mobile phone which has an email facilty.  Everytime I ask the phone to send and receive an email I receive the following message:

Invalid certificate error: a certificate has expired or has invalid validity date. Certificate details, serial number: 11 21 FB 2A 7C 6A 4A 08 34 0A D3 DA C1 61 B7 04 DD 21  Version2 Issuer Globalsign organisation. Validation CA-G2 Global sign nv-sa BE Subject: pop3.live.com microsoft corporation redmond wahsington US valid from 9.3.2013 Valid to:9.3.2016 etc


This is a regular occurrence and is now popping up all the time even when texting and using internet. I have contacted Orange who advise me this is a server problem with either Microsoft/hotmail and should contact you.
Please could you advise.
