I have a certificate which is out of date GlobalSign Root CA on my W995, expired 28-Jan-14. I installed the replacement one and it was showing in the Trusted Certificates folder, however I still get an error message: 'Trusted certificate expired or date in phone incorrect. Continue with the secure connection?' I have to confirm 'Yes', which therefore interrupts automatic checking and downloading of emails (my exchange active sync is not working either on hotmail). Do I need to delete the old certificate for the new one to work? Both are set as 'Active' However, whilst I have an option to delete the new downloaded certificate, the option is greyed out on the old certificate. I have now deleted the new certificate as it did not make any difference.
