Hi,
We currently have a AD Domain as ABC.COM and wanted to setup Exchange 2010 in saperate forest ex: Exchange.COM. We are thinking to use AD federation to access Exchange 2010 mailbox in Exchange.com using existing AD i.e ABC.COM.
Kindly suggest how we can test and setup this. Bottom line is that we do not want to setup Exchange 2010 in exisitng forest however users should be able to access mailbox using exisitng credentials. You can think as a private cloud for specific setup.
Regards Mahesh
