Exchange 2010 SP2 Rollup 4

Today the Exchange Team released Rollup 4 for Exchange Server 2010 Service Pack 2 (KB2706690). This update raises Exchange 2010 version number to 14.2.318.2.

Here’s the list of changes in this Rollup:

  • 2536846 Email messages sent to a mail-enabled public folder may be queued in a delivery queue on the Hub Transport server in an Exchange Server 2010 environment
  • 2632409 Sent item is copied to the Sent Items folder of the wrong mailbox in an Exchange Server 2010 environment when a user is granted the Send As permission

  • 2677727 MRM cannot process retention policies on a cloud-based archive mailbox if the primary mailbox is in an on-premises Exchange Server 2010 organization
  • 2685001 Retention policies do not work for the Calendar and Tasks folders in an Exchange Server 2010 SP1 environment
  • 2686540 Journal report is not delivered to a journaling mailbox in an Exchange Server 2010 environment
  • 2689025 Performance issues when you use the light version of Outlook Web App in an Exchange Server 2010 environment

  • 2702963 The “Open Message In Conflict” button is not available in the conflict notification message in Exchange Server 2010
  • 2707242 The Exchange Information Store service stops responding on an Exchange Server 2010 server
  • 2709014 EdgeTransport.exe process crashes intermittently on an Exchange Server 2010 server
  • 2709935 EdgeTransport.exe process repeatedly crashes on an Exchange Server 2010 server

  • 2726897 Event 14035 or Event 1006 is logged when Admin sessions are exhausted in an Exchange Server 2010 environment

In addition to these fixes, this Rollup also includes a fix for the WebReady security issue described in Microsoft Security Bulletin MS12-058 (KB2740358).

Note that  This Rollup includes changes enabling Retention Tags for Calendar Items and Tasks (see KB2685001). If you wish to retain pre-SP2RU4 functionality, implement the following registry key on each Mailbox server:
HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeMailboxAssistants\Parameters\ELCAssistantCalendarTaskRetentionEnabled=0x00000000 (REG_DWORD); default value is 1. More information on possible implications at the Exchange Team’s blog here.

Important: Be advised that it is reported that installing MS12-058 (KB2740358) means Rollup 4 will be installed on your system. This applies to manual installations but updates installed through Windows Update / WSUS as well, which might pose a challenge (or better, dilemma) for security departments (Thanks to Paul Bendall).

Those who use WSUS to deploy security updates or manually apply MS12-058 will be inadvertently applying Exchange 2010 SP2 RU4 as the security

As of this Rollup, its no longer required to disable/re-enable ForeFront Protection for Exchange using the fscutility to be able to install the Rollup properly. However, if you want to remain in control, you can disable ForeFront before installing the Rollup using fscutility /disable and re-enable it afterwards using fscutility /enable.

Note that Rollups are cumulative, i.e. they contain fixes released in earlier Rollups for the same product level (RTM, SPx). This means you don’t need to install previous Rollups during a fresh installation but can start with the latest Rollup.

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. For the correct procedure on how to update DAG members, check here.

  1. Michel, curious about disabling/enabling Forefront during the installation of UR4. Is that something you experienced in a lab environment, at a customer or is it the recommendation (best practice) of MS? Or is it another in a growing list of the many side affects found when applying the updates? If it is known by MS, will you provide the article referencing it?

    Cheers.

    • Rollup 4 can disable ForeFront for you; however, if you want to remain in control you can do so yourself. Reason for disabling/enabling is that pre-Rollup 4, the Information Store and Transport services may not start after installing the Rollup. It is mentioned in all of the installation notes accompanying Rollups.
