Exchange Update Rollups and Service Pack released today

Exchange 2007 Service Pack 3 Update rollup 13 is now available for download from here. Read the corresponding KB2917522 for bugfixes which is almost zero.

Also Exchange 2010 SP3 UR5 was released and can be downloaded from here. The corresponding KB2917508 contains some interesting bugfixes and new functionality.


Exchange 2013 Service Pack 1 which is essentially CU4 but is named SP1 instead. it contains some new functionality such more DLP functionality and the big one, support for Windows Server 2012 R2 Domain Controllers, raising both Domain Function and Forest Functional Level to 2012R2, and installing Exchange 2013 SP1 on Windows 2012 R2.

Other new stuff is that Edge server is back. A new protocol used for client/server communication is introduced called MAPI/HTTP which is very similar to MAPI over RPC which is then tunneled over HTTP so in short, communication don’t rely on RPC layer which gives some advantages when it comes to authentication and reconnection of clients. It is disabled by default and you also need Outlook 2013 SP1 for leverage MAPI/HTTP.
If you use TMG or any other reverseproxy that filter on URL’s you need to add ‘/mapi/*’ as an allowed URL.

As usual there is the regular schema and AD prep stuff to do before you install the first SP1 server.
