If your organization is considering an email archiving solution then I suggest testing a couple of solutions before taking any decisions. The features of email archiving solutions that you should look for need to include; an automated archive mechanism, a faster search mechanism for eDiscovery, Active Directory support, fast mailbox and email restore mechanism and any other requirements that may be specified by local regulations or laws if this is your case.
