Install Exchange 2013 Cumulative Update 9

Microsoft has released Exchange 2013 CU9, three months after the release of CU8. Microsoft has made a solid Cumulative Update this time (just like CU8 by the way) and during testing not much issues were found.

There aren’t any new features in this Cumulative Update, and personally I don’t expect any new features anymore in future Cumulative Updates either. All development efforts at Microsoft are currently targeted towards Exchange Server 2016.

The official announcement of CU9 can be found on The Exchange Team Blog, CU9 itself can be downloaded from the Microsoft Download Center, just as the accompanying CU9 UM Language Packs.

Exchange 2013 Cumulative Update 5

Microsoft recently released its quarterly update for Exchange Server 2013, Cumulative Update 5 (CU5), and the successor of Exchange 2013 Service Pack 1 (which is Cumulative Update 4 under the hood).

Just start directly installing Exchange 2013 CU5.

Upgrade to Exchange Server 2013 RTM CU2

Now that Microsoft has released Exchange Server 2013 RTM CU2 it’s time to have a closer look at installing this Cumulative Update.

In contrast with the previous Update Rollups as we’ve seen in Exchange 2007 and Exchange 2010, which were only a set of hotfixes bundled together, a Cumulative Update is a full version of the product. So, it is now possible to install an Exchange 2013 server from scratch using the CU2 download.

Another advantage of a CU is that Microsoft can bundle new functionality into the product, even Schema changes are possible (as a matter of fact CU2 does include a number of Schema changes) but also the Configuration container in Active Directory can be changed.
