Outlook 2013 Security Update breaks Out of Office for Exchange 2007 Mailboxes


Issue

In the past two weeks I’ve had two customer environments come to me with the same issue. Random Outlook 2013 clients are unable to configure their Out Of Office settings. Specifically, they would get an error message when trying to open their OOF settings to set them. Some users had no issue while others got the error. Both environments were Exchange 2007 on latest Service Pack/Update Rollup & had a few users running Outlook 2013; only a few of which were having this issue.

Resolution

After some searching online I found this thread pointing to a recent (November 12th 2013) Outlook Security Update as the culprit. In my case, after uninstalling KB2837618, rebooting the client, & re-creating the Outlook Profile (a profile repair did not work) then Out Of Office started working again.

In fact, after reading the full KB it appears this is a known issue:

  • If you are using Outlook to connect to a Microsoft Exchange Server 2007 mailbox:
    • You receive an error message that resembles either of the following when you try to configure Automatic Replies (Out of Office): 
      Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later. 
    • You cannot retrieve Free/Busy data for calendar scheduling.
    • Add-ins that use the Account.SmtpAddress property no longer work.

    These features rely on an underlying Autodiscover technology. After you install this security update, Autodiscover may fail for Exchange 2007 configurations. Therefore, Outlook features that rely on Autodiscover will also stop working.

    Microsoft is researching this problem and will post more information in this article when it becomes available.

It appears the reason only random Outlook 2013 clients were experiencing the issue was because not all of them were up to date via Microsoft Update. Of course most Exchange folks will never read all the release notes of KBs pushed to Outlook via Microsoft Update ahead of time. I suppose the answer to an actual admin (which I am not) who complains will be “What, you don’t use WSUS & test every update for Office?” 😀

Update:

As Jim Morris pointed out in the comments below, the issue is addressed in http://support.microsoft.com/kb/2850061

Problem with Exchange MMC Snap-in after April 11\2011 updates.

We have seen a recent rash of issues with Exchange MMC after April 11 updates, this is due to a .net change in the latest updates.

This issue is very specific to a system with

  • .NET Framework 3.5 Service Pack 1
  • .NET Framework 2.0 Service Pack 2
  • Windows Vista Service Pack 2 or Windows Server 2008 Service Pack 2
  • April 11 windows updates. (Specifically 2449742 or 2446709)

This problem occurs when the broken version of Hotfix 979744 is installed on your computer, and when security update 2449742 or 2446709 (part of security bulletin MS11-028) is installed in the affected environments, this problem generates the issues that are described in the "Symptoms" section.
