Outlook 2010 Client having autodiscover issues
Posted on 2011-02-17
I am having an issues where one outlook 2010 client on our network is having a problem with their autodiscover.
It all started then they were getting a certificate error to say that the name on the site didnt match that on the certifiate. at the top of the certificate the url was autodiscover.domain.co.uk
Now our autodiscover IIS directory is set to its default, so it listens on the autodiscover.domain.local url and we have a SAN SSL certificate with both the external and internal autodiscover domain in it, along with a few others.
I have checked this is still being used in exchange for IIS, and that it is still in the certificate stre with its private key. All other clients work fine except this one, which seems to want to talk to the exchange server using the autodiscover.domain.co.uk domain rather than the autodiscover.domain.local domain it should, therefore a mismatch error.
Also note the client when creating a new outlook profile, cannot autodiscover their account either. I have repaired office 2010 on the client but no results from that.
