Not sure what you mean by clustering... if you are referring to mailbox resiliency (a.k.a. Database Availability Groups), that feature is available on both Exchange Standard and Exchange Enterprise, albeit for differing numbers of mailbox databases per edition. -----Original Message----- From: Joseph Heaton [mailto:jhea...@dfg.ca.gov] Sent: Tuesday, December 08, 2009 12:55 PM To: MS-Exchange Admin Issues Subject: RE: Differences between Exchange Standard and Enterprise Michael, Yes, asking about 2010. I've been trying to poke around Microsoft's website for this information, but what I have found is kind of vague. Are there any differences in clustering capabilities between the two versions? Also, do you know of a spot anywhere that lists the differences in the CALs? >>> "Michael B.

For the _SERVER_ license, that and availability of the external connector are the only differences. For the _CAL_, there are loads of differences. Do note that mailbox resiliency requires Windows Server Enterprise, even though the feature is available on both Exchange Standard and Exchange Enterprise. -----Original Message----- From: Joseph Heaton [mailto:jhea...@dfg.ca.gov] Sent: Tuesday, December 08, 2009 12:21 PM To: MS-Exchange Admin Issues Subject: Differences between Exchange Standard and Enterprise I was looking at Microsoft's site for this, and the only real difference I could find was the number of mailbox databases possible. Is this the case, or are there other things that I didn't see? Thanks, Joe
