We have installed 2013 Mailbox and CAS Server on separate boxes into our 2010 environment. We have migrated a few users and it seems autodiscover does not configure Outlook anywhere on the Outlook 2010 client. If we configure this manually the user can connect and view mail. Outlook web access is fine, certificates appear to be working as we can manually configure Outlook and it is ready mail very well. We are running Exchange 2013 CU3, and have installed the certificate on the CAS. the autodiscover dns entry has been changed to point to the 2013 CAS.
Is this a common problem and what can we try to do to resolve this issue ?
I've read a few different posts and looked at authentication of virtual folders (still default setup), certificates (added new certificate from company CA). Any ideas ?
