Yesterday, the Microsoft Exchange Team has released Cumulative Update 1 for Exchange 2013 RTM. CU1 is the minimum version of Exchange 2013 required for on-premises coexistence with supported legacy Exchange Server versions. The final build number for CU1 is 15.0.620.29.
This is the Exchange 2013 product level required for co-existence with previous versions of Exchange, being Exchange Server 2010 SP3 or Exchange Server 2007 SP3 Rollup 10.
The Exchange Team provided a description of the major changes in CU1. You will find the announcement here;
Here are some of the major changes in CU1:
- Includes Address Book Policy Routing Agent (info);
- Allows group memberships to be managed by groups (again, as it was possible in Exchange 2007 but not in Exchange 2010);
- Access to Public Folders you have added as favorites via your favorites menu either in Outlook or Outlook Web App (still no regular Public Folder tree access though);
- EAC has been enhanced and now includes Unified Messaging management and migration options;
- Many probes, monitors, and responders have been updated and improved over the RTM release;
- Get-HealthReport cmdlet has been streamlined and its performance has been optimized;
- Supports the Exchange Server 2013 Management Pack for SCOM 2007 R2 and SCOM 2012 (due at a later date);
- High Availability changes
