Exchange 2010 SP3 RU7 Released

The Exchange team today announced the availability of Update Rollup 7 for Exchange Server 2010 Service Pack 3. RU7 is the latest rollup of customer fixes available for Exchange Server 2010. The release contains fixes for customer reported issues and previously released security bulletins.  For example, the security issue that was addressed in Exchange 2010 SP3 RU4 is contained in RU7.

This is build 14.03.0210.002 of Exchange 2010, and KB2961522 has the full details for the release

Note that this is for the Service Pack 3 branch of Exchange code.  Why?  Exchange 2010 SP2 exited out of support on the 8th of April 2014 and will no longer receive updates.

Important Notes

Now, before we rush off to download and install this there are a couple of items to mention!

• Test the update in your lab before installing in production.  If in doubt test…

• If the Exchange server does not have Internet connectivity then this introduces significant delay in building the Native images for the .Net assemblies as the server is unable to get to http://crl.microsoft.com.  To resolve this issue, follow these steps:

  1. On the Tools menu in Windows Internet Explorer, click Internet Options, and then click the Advanced tab.

  2. In the Security section, click to clear the Check for publisher's certificate revocation check box, and then click OK.

  We recommend that you clear this security option in Internet Explorer only if the computer is in a tightly controlled environment. When setup is complete, click to select the Check for publisher’s certificate revocation check box again.

• Update Internet facing CAS servers first

• Backup any OWA customisations as they will be removed

• Test (yes technically this is in here for a second time but it is important!)

Cheers,
