after going over all related questions in this site and others; as well as going over all related MS support articles I could find I have no other option then to post the question myself.
Environment is Exchange 2007 (1 CAS and 1 CCR Cluster), AD is mixed 2003/2008
Clients are all Outlook 2007 or higher
We are using a countryspecific subdomain for emails so that customers can easely find out to which country/site they are mailing.
EMail adrresses are @countrycode.company.com with each of the having @company.com as secondary address.
The certificate is hence registered to mail.company.com
Whenever clients that have @countrycode.company.com connect to Outlook Anywhere they get the annoying popup saying "The name of the security certificate is invalid or does not match the name of the site" since it is looking for autodisover.COUNTRYCODE.company.com
There is too many countries to include them all into one certificate
Any resolutions please ?
