Hi,
We still have a mixed Exchange 2007 SP3rollup b (on Windows Server 2003 R2) and Exchange 2010 SP3 rollup 6 (on Windows Server 2008 R2) environment with TMG2010 servers (on Windows Server 2008 R2).
Because of the poodle attack we want to disable SSL v3 and only allow TLS on the TMG-servers.
When we configure this on the TMG-servers, ActiveSync and OWA don't work anymore for users with mailboxes on the Exchange 2007 environment.
It only works for the mailboxes on the Exchange 2010 environment.
What do we have to configure on the Exchange 2007 CAS servers to make it work?
Thanks
