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.

ECP do not show all Organization Units in Active Directory

You may have seen this when you use Exchange 2013 ECP to create a mailbox and want to select a specific OU. Then for what it looks the OU picker don’t show all OUs, only some of them are shown.
Reason is that the ECP webapplication has a limit of not showing more than 500 OUs, rest of them wont simply be shown.
Don’t cry, there is a solution if you have some CPU cycles to spare. Edit the “web.config” in the ECP directory. Default path is “C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ecp\”.
In the appsettings section, add the XML element
<add key="GetListDefaultResultSize" value="5000" /> where the 5000 is number of OUs you want to be shown.
When done recycle the MSExchangeECPAppPool to make ecp webapplication read the configuration and have it live and kicking.
