UPDATE (December 12th, 2014): Exchange 2010 SP3 Rollup 8 v2 is released, addressing the issue mentioned below in the initially published version. The new version number is 14.3.224.2 (was 14.3.224.1). You can download RU8v2 here.

UPDATE (December 10th, 2014): Exchange 2010 SP3 Rollup 8 has been pulled after discovery of Outlook MAPI issues. It is currently recommended not to deploy RU8 and when you have installed RU8, to revert to RU7 to prevent walking into this issue. Other protocols, such as EAS or IMAP4, as unaffected which is why you might not encounter this problem immediately.

Today the Exchange Team released Rollup 8 for Exchange Server 2010 Service Pack 3 (KB2986475). This update raises Exchange 2010 version number to 14.3.224.1.

This Rollup contains a security update to fix a potential elevation of privilege issue (bulletin MS14-075), as well as the following fixes:

Notes:

• If you want to speed up the update process for systems without internet access, you can follow the procedure described here to disable publisher’s certificate revocation checking.
• If you got a DAG and want to properly update the DAG members, check the instructions here.
• Rollups are cumulative per service pack level, i.e. they contain fixes released in earlier update Rollups for the same product level (RTM, SP). This means you don’t need to install previous Rollups during a fresh installation but can start with the latest Rollup package.

As with any Hotfix, Rollup or Service Pack, I’d recommend to thoroughly test this rollup in a test and acceptance environment first, prior to implementing it in production.
