Microsoft has released Update Rollup 10 for Microsoft Exchange Server 2007 Service Pack 3 (SP3) that is dated February 12, 2013 and includes the following new feature:
- Coexistence with Microsoft Exchange Server 2013: You can now install Exchange Server 2013 in your existing Exchange Server 2007 organization. To do this, you must install Microsoft Exchange Server 2013 Cumulative Update 1 (CU1). This is because you cannot install Exchange Server 2013 in your existing Exchange Server 2007 organization by using the Exchange Server 2013 RTM installation media.
