Exchange 2013 CU17 and Exchange 2016 CU6

On June 27, 2017 Microsoft has released its quarterly updates for Exchange 2013 and Exchange 2016. The current version is now at Exchange 2013 CU17 and Exchange 2016 CU6. Typically I don’t pay that much attention to this, all new developments seem to be for Office 365 and very little developments for on-premises Exchange deployment. But this time there are some interesting things I’d like to point out.

A couple of days before the release of Exchange 2016 CU6 Microsoft blogged about Sent Items Behavior Control and Original Folder Item Recovery. With the Sent Items Behavior Control, a message that’s sent using the Send As or Send on behalf of permission is not only stored in the mailbox of the user that actually sent the message, but a copy is also stored in the delegator mailbox sent items. This was already possible for shared mailboxes, but now it’s also possible for regular mailboxes (like manager/assistant scenarios).

The Original Folder Item Recovery feature is I guess on of the most requested features. In the past (before Exchange 2010) when items were restored after they were deleted, they were restored to their original location. With the Dumpster 2.0 that was introduced with Exchange 2010 this was no longer possible, and items were restored to the deleted items folder. In this case the items had to be moved manually to their original location. With the introduction of the Original Folder Item Recovery the restore of deleted items again takes place in the original folder.

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). It is a Cumulative Update, so it contains all fixes, features and functionality of earlier CU’s so if you’re installing a fresh Exchange 2013 server or upgrade for example from CU2 there’s no need to install SP1 first. 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.
