Microsoft Exchange Server 2013 RTM gets first Cumulative Update

In December, Microsoft launched the RTM version of Exchange Server 2013 to the general public. Today, the company announced that the first Cumulative Update (CU1) for Microsoft Exchange Server 2013 RTM is now available to download.

In a post on the Exchange blog, Microsoft announced some of the new features, including a way to access any Public Folders that have been added as favorite in both Outlook or the Outlook Web App. It also adds a new Address Book Policy Routing Agent, a way for groups to manage groups and more. Naturally, there are a number of big fixes in this new version. The full release notes can be checked out at Microsoft's website.

This will also be the first Cumulative Update for Microsoft Exchange Server 2013 under a new release model. Microsoft stated:

Unlike previous versions, cumulative updates do not use the rollup infrastructure; cumulative updates are actually full builds of the product, meaning that when you want to deploy a new server, you simply use the latest cumulative update build available and do not necessarily need to apply additional Exchange Server updates.

This will be the first release in Microsoft's plans for a quarterly release schedule in terms of its Exchange Server 2013 cumulative updates.

I just upgraded us from SBS 2003 R2 in September and was kinda waiting for Exchange 2013 to go RTM but guess it didn't come fast enough. Did Exchange 2010 and that's working as expected.

I am liking what I see with EX2013 though, guess we'll be missing out on this one for a bit till 2015

Yeah this was long overdue!

I couldn't migrate my Exchange 2010 environment without this update... Still strange to me that Exchange 2013 shipped with no ability to migrate existing Exchange orgs.

The new Outlook Web App is awesome.

yeah, we are currently stuck on exchange 2010, which sadly we just put in a year and a half ago... we were waiting for the first set of updates and a little after that to see how well they play out with other organizations

Smart idea. I didn't have any issues, but since Microsoft decided to ship Exchange 2013 without any support for migration and they were late shipping CU1 due to issues with Exchange 2013 coexisting with 2010... It seems the whole product was rushed.

A nice idea with the CU. They did this with Service Packs previously where the whole update was actually the installation files. Sadly you still had to install the rollups to get up to date.

Sweet!!! Can't wait to get this update at work We upgraded to 2013 recently and it's been great, but these updates sound like it'll be even better
