Trials over the weekend of the Outlook Anywhere didn't yield the results we had hoped. Now internal OLK 2010 clients are getting a Proxy Error Code 10 when the OLK client is started, and the clients cant connect to their mailboxes. I suspect this is to do with our configuring Exchange 2013 then returning to the original config.
The Error
Title : Microsoft Outlook
Detail : There is a problem with the proxy server's security certificate. The name on the certificate is invalid or does not match the name of the targe site "servername.domain.local" Outlook is unable to connect to the proxy server. (Error Code 10)
What did I do : in Exch2013 - Server - OLK Anywhere - there are 3 fields and a check box
- External host name - was blank prior to testing, added external domain name during testing mail.ourdomainname.com.au then cleared the field when testing was complete.
- Internal hostname - was unchanged from servername.doman.local.
- Authentication method - was unchanged, but I admit I may not have noticed if it did change due to the FQDN being added in the 1st field.
- Allow SSL Offloading - was checked and still is
My suspicion is that by configuring this feature as a test, that parts of Exch2013 may also need to be reset that aren't visible via the EAC. As an FYI the external OurDomainName.com.au is current, and the SSL Cert is current, however the SSL only covers the external domain name Mail.OurDomainName.com.au
