Hi,
I have the an exchange 2010 org with the following servers:
2 HUB/CAS Servers (CAS array with WNLB)
2 Mailbox (DAG)
I want to install the UM Role and I want to know is there any consideration when placing the role (except the performance issue).
Is there some cases that are not supported by MS?
What would be the best choice? to install the UM role on a HUB/CAS Server or on a Mailbox Server?
Thank you!
