Dear all,

I would like to know if somebody is using the mailbox-level and item-level 
restoration with Exchange 2010. On the install guide, they said:

“[…] the Client Access  Server Role must also be configured to run Mailbox 
Restore operation on Exchange Server 2010[..]”

My question are:
   1. Should I install TDP for Exchange on the CAS server as well?
   2. Should I install the Microsoft Exchange Server MAPI Client and 
Collaboration Data Objects 1.2.1 (MAPI) version 6.5.8147.0 (or later) on all 
Mailbox Server Role and Client Access Role?

If I understand well, The TDP for Exchange must be install only on the Mailbox 
Server Role. I don’t need it on CAS and HUB. I’m I right?

Thank you all for your help.
