Certificate Error in Outlook 2010

ReverendRob

Hi there,

I upgraded our Web Appliance to V4.0.2.2 in gradual steps yesterday (1st June 2015) and we have suddently started getting a certificate error in Outlook 2010 claiming that an untrusted certificate has been issued by the Web Appliance to autodiscover.domain.com (see attached photo). The strange thing is the certificate was issued on the 27th May, several days before I did the box upgrade.

I have tried enabling Certificate Validation (which we don't tend to use) but it makes no difference that I can tell.

Is anyone else getting anything odd like this? Any ideas where to start looking?

Cheers.

    I didnt want to make a new thread as this has already been brought up but i work for a primary school and we currently have a ws500 web appliance which was upgraded to version 4.0.2.3 last night.

    The version prior to the upgrade was 3.9.4.1. It did 6 updates and when it was on version 3.9.4.1 we had no issues when opening outlook 2013. Now on the latest version it keeps coming up with security alert messages three times on every user that has outlook 2013. One for a mailserver, the second for one of our servers and the third for a domain name under our office 365 cloud.

    Is there anyway to fix this as i have already contacted someone from sophos technical support who looked at the backend and didnt do anything?
