Earlier today we re-released the following Rollup Updates. These updates address an issue in which digital signatures on files produced and signed by Microsoft will expire prematurely, as described in Microsoft Security Advisory 2749655. Also see Security Advisory 2749655 and timestamping on the Security, Research & Defense blog.

The re-released Exchange 2010 SP2 RU4 includes the following additional fix:

2756987 Only one result is returned after you click "view all results" in Outlook 2010 or in Outlook 2013 in an Exchange Server 2010 environment

It is not required to uninstall the previous rollups to install the re-released rollups listed above.

  • @Sven: The issue mentioned in that thread not a known issue.

  • We should uninstall existing Update Rollup 4 before installing the v2!

  • None of the links or articles give the premature expiration date.  So from a change management aspect, how long do I have to get these updates approved and installed before the previous signed binaries expire?

  • If Update Rollup 4-v1 for Exchange Server 2010 SP2 is already installed on our systems, we do not need to install this v2 version?  Problem was only with the original installation v1 file?

  • I've got the same problem as Ron Mitchell.

    WindowsUpdateLog says notthing, EventViewer the same. RU4 (V1) is already installed.

    Any Idea where to look for the error?

  • KB2756485 will not install on any of my systems.  During the installation, it fails and just says "ended prematurely"

  • When do these signatures expire exactly ?

    Can I skip this one and wait for RU5 ?

  • What about this problem, is it known?

  • @Mike: You don't need to uninstall the original rollup to install the re-released one.

  • Treat this like an Interim upgrade an uninstall original RU8 first like the last re-release or install over the top?
