Exchange Server 2013 CU7

1 Comment

On Tuesday December 9, 2014 Microsoft released Exchange Server 2013 Cumulative Update 7 and the UM Language Packs for Cumulative Update 7, 105 days after the release of the previous CU6 update. This release is a little overdue because of a last minute issue that was found moments before the original release date of CU7. As long as it improves the quality of the release this shouldn’t be a problem though.

CU7 contains fixes for issues reported by customers, including the Russian Time Zone issue and fixes for issues identified in MS14-075. Updates for MS14-075 are also available for Exchange Server 2013 Service Pack 1 and Exchange Server 2013 Cumulative Update 6. Because of the Microsoft (N-1) support policy this hotfix won’t be available for CU5.

I am always amazed by the amount of customers running Exchange 2007 or Exchange 2010 and NOT using Autodiscover. Their response is always “we don’t need it” and “we configure the Outlook profile manually”. In Exchange 2007 and Exchange 2010 you can get away with this (you cannot with Exchange 2013 and Autodiscover is mandatory) but when you want to implement a hybrid scenario with Exchange online you really need Autodiscover since Exchange Online uses Autodiscover to find relevant information regarding your on-premises Exchange environment.

Recently a customer with Exchange 2010 wanted to build a hybrid environment with Exchange Online, and one of my first findings was the lack of Autodiscover. So, after configuring their Exchange environment and creating the necessary DNS records Autodiscover was working properly as shown in the following picture:

When moving mailboxes from Exchange 2003 or Exchange 2007 to Exchange 2010 the move request finishes, but with a status of CompletedWithWarning:

The mailbox is moved to Exchange 2010, but the time to finish the actual migration takes a long time. The first reports of this issue I’ve seen came with Exchange 2010 SP2 RU3.
