We are in the process to migrate from Exchange 2007 CCR Cluster to Exchange 2013 DAG. We publish OWA, EAS and Outlook Anywhere and use a TMG for that purpose.
Now we would like to publish Outlook anywhere (OA) with Ntlm and Kerberos Constrained Delegation on the TMG, where we do a Preauthentication. This works fine for Mailboxes on EX13, but not for EX07 MBX.
Is there any way that we can do that, I mean publishing OA with NTLM (Kerberos Constrained Delegation) on the TMG for Mailboxes on EX13 and on EX07.
Basic Authenticaton works in this OA coexistence szenario but not NTLM with Kerberos.
Any advice would be appreciated.
