Hi, I have Exchange Server 2003 running on my domain, with about 50 Outlook 2007 clients. One client is receiving an autodiscover pop-up when he opens Outlook, which says that there is a problem with a site's security certificate and that the name on the security certificate is invalid or does not match the name of the site. The domain that it refers to is the company website which there is a link to in the email signature.
Everything that I can find on this subject indicates that the autodicover service was introduced in Exchange 2007, which is not running on my network or domain. I went into IIS on the Exchange Server to look for MSExchangeAutodiscoverAppP
ool and sure enough it does not exist. None of the other Outlook clients are receiving this error, and many of them have the same domain in their signature.
How can I stop this from occuring, and where might it be coming from? I am considering doing an uninstall and reinstall of Office 2007.
