Official fix list for Outlook 2007 SP2 both the summary and the complete list

Here’s the official fix list for Outlook 2007 SP2 both the summary and the complete list. We’ve published it here for easy reference instead of hunting around Microsoft’s web site and an Excel worksheet.

This list does NOT include details of past hotfixes, security and other updates that are also bundled into Service Pack 2.

The list isn’t complete – Microsoft says there are other reliability, security and what they feel are minor bugs they consider ‘too specific’ to be publicly disclosed.

The Outlook 2007 SP2 details come in three parts. The summary, the official list supplied in an Excel worksheet and a KB article. We’ve published the summary and full list below.

The KB article Outlook 2007 improvements in the 2007 Office suite Service Pack 2 has a commendably well-written summary of the changes.

It’s nice to see that the delay in starting Outlook 2007 the first time after applying Service Pack 2 is now given the prominence it deserves.

As Office Watch suggested – the February 2009 Cumulative Update had most, if not all, the Outlook fixes slated for Service Pack 2. So don’t be surprised if you get a little sense of déjà vu.


  • Performance improvements that apply to the following general responsiveness areas:

    • Startup
      Removes lengthy operations from initial startup.
    • Shutdown
      Makes Outlook exit predictably despite pending activities.
    • Folder View and Switch
      Improves view rendering and folder switching.

  • Calendar improvements
    Improves underlying data structures and the general reliability of calendar updates.
  • Data file checks
    Greatly reduces the number of scenarios in which you receive the following error message when you start Outlook:

“The data file ‘file name‘ was not closed properly. This file is being checked for problems.”

  • Search reliability
    Improves search reliability when you use SP2 with Windows Desktop Search 4.
  • Improvements to Really Simple Syndication (RSS)
    There are now fewer duplicated items.
  • Object Model improvements
    Now contains many customer-driven fixes.


Complete list

  • A local change to a meeting item is not synchronized to the server. Sometimes the meeting disappears, and the meeting is moved to the local failure folder.
  • A meeting that is copied from a shared calendar does not indicate that the meeting is a copy. SP2 adds “Copy:” to the subject line.
  • A reminder cannot be dismissed on a corrupted meeting.
  • A reminder cannot be dismissed or made to snooze. Therefore, a restart of Microsoft Outlook may be required to dismiss the reminder or to make the reminder snooze.
  • A reminder dismissal occurs as a background task. With SP2, Outlook instantly restores user interface responsiveness after a reminder.
  • Administrators cannot use Group Policy settings to block the export of contacts from the global address list (GAL).
  • After a series update, if an instance is moved to timeslots that were previously occupied, attendees may lose an instance.
  • After you add many RSS feeds, Outlook crashes.
  • After you discard some changes to a meeting that you own, an update for that meeting may be sent out when you close Microsoft Outlook.
  • An entry for a Calendar or Contacts folder is duplicated in the Calendar or Contacts list, respectively. Only one of the duplicated links for a folder will work.
  • Attendees can cancel meetings on behalf of organizers in Outlook 2007.
  • AutoDiscover in Outlook fails if the user domain names are too long.
  • Bursts of write operations are flushed to the disk too frequently. This causes frequent pauses and the user interface becomes unresponsive.
  • “Consider the following scenario.

      • 1. An organizer sends a recurring meeting.
      • 2. The organizer moves the instance to a different day.
      • 3. Attendees accept the series and the update.
      • 4. An attendee proposes a new time.
      • 5. The organizer accepts the new time proposal and sends the update to all attendees.

    • In this scenario, the organizer’s time is reverted to the original one.”

  • “Consider the following scenario.

      • 1. You run a search in a folder of Outlook 2007.
      • 2. You run the search in “”All Mail Items.””
      • 3. You click the “”show all results”” bar.

    • In this scenario, the bar does not disappear.”

  • Data file checks occur too frequently, and data file checks to checkpoint and resume from a previous session are enabled.
  • Downloading a large message can block the user interface.
  • Duplicate calendar entries, duplicate attendees, or old-style conflicts occur when you use more than one client or run against Exchange Server 2007 or later versions.
  • Exceptions to a recurrent meeting show duplicate attendees.
  • Folder sort indexes were not saved in certain cases. This causes the index to recompute the index for each folder switch.
  • Form regions are sized to have 0 height or width when they are loaded. After the form regions are loaded, they are invisible.
  • If a distribution list (DL) that includes a meeting organizer is removed from a meeting, the organizer receives a cancellation. The organizer can remove the meeting without sending a cancellation. Additionally, a meeting that does not have an organizer cannot be updated or canceled.
  • If a distribution list is a member of the attendees, an attendee of that meeting can receive a cancellation unexpectedly. This problem occurs when the “Send updates only to added or deleted attendees” option is enabled.
  • If a meeting is corrupted, an attendee becomes the organizer and can cancel the meeting.
  • If a Windows Vista user connects to an Exchange Server by using RPC/HTTP, enters his or her user name and password, and then selects the “Remember my password” option, the next time that Outlook connects, the user is still prompted for credentials.
  • If an RSS feed item download is interrupted, the RSS feed items that are deleted by users come back.
  • If the Mailto hyperlink contains international characters, the hyperlink does not work.
  • If the organizer of a meeting who is a member of an external distribution list sends a meeting request to that external distribution list, the organizer becomes an attendee.
  • If the store providers are disconnected early, the Outlook.exe process becomes unresponsive for a very long time.
  • If you act on meeting requests before the Calendar folder is synchronized, the meetings response states are reverted. For example, the declined meetings come back. Or, meetings are duplicated.
  • If you change the file name when you save a file from an Outlook attachment, the extension is lost.
  • If you click Remove from Calendar for a canceled instance of a recurring meeting, the whole series is deleted.
  • If you update the status bar during an Outlook synchronization or folder switch, Outlook becomes unresponsive.

  • Inefficient processing occurs in a loop during intermittent network connectivity.
  • Items in search folders sometimes disappear and do not reappear.
  • Licensing validation can cause Outlook 2007 to become unresponsive at first startup after an Outlook installation or upgrade.
  • More logging capabilities are available when logging is enabled. This can help the support team investigate issues with calendars.
  • Moving lots of items causes a long pause in the user interface and high CPU usage.

  • Outlook adds itself again to the indexing options control panel as a searched scope after the user deselects Outlook.

  • Outlook may become unresponsive shortly after startup if an RPC is issued to the Exchange directory server.
  • Outlook resets all e-mail Favorite Folders during a startup after a crash.
  • Outlook stops indexing mounted PSTs when a Classic Online mode account is used.

  • RSS items are sometimes duplicated.
  • Server-relative links in SharePoint RSS feeds do not work in Outlook.
  • Some users may not change the recipient list when they reply all on a digital rights management (DRM) protected item in the Sent Items folder.
  • Sometimes an update is sent to all attendees even though you chose to send the update only to attendees who were added or updated.
  • Sometimes the Outlook calendar displays appointments and meetings in black text on a black background when you use high-contrast mode.
  • SP2 includes a solution to process internal change notifications in the background. This enables the user interface to be more responsive to user input when significant background processing occurs, such as synchronization or indexing.
  • SP2 provides a more efficient date sort for all folders that is maintained regularly to sort dates very quickly.
  • Synchronization conflict resolution frequently results in creating Exchange Server conflict items.
  • Synchronization with SharePoint could cause error logs to be generated even when logging is disabled.
  • The new mail notification window unnecessarily reloads the delivered messages to check for additional and rarely used properties.

  • Voice mail items display the sender’s name in non-Unicode fonts.
  • When multiple processes are accessing the same data file by using MAPI, the Outlook user interface does not receive the highest priority access to data files.
  • When Outlook 2007 restarts, it does not reset the AutoDiscover counter. The counter may not run for at least 6 hours.
  • When Outlook builds information to display new mail notification alerts, Outlook can become unresponsive periodically.
  • When Outlook is syncing with multiple RSS feeds, Outlook crashes.
  • When the indexing process encounters problems, many event logs are generated, and CPU usage increases.
  • When three or more processes access a MAPI store, and one process stops unexpectedly, Outlook 2007 becomes unresponsive.
  • When you add roaming SharePoint lists to a new Outlook profile, Outlook keeps adding duplicates of personal folders.
  • When you click a hyperlink, the user interface becomes unresponsive during a check of the Internet proxy server settings. These checks now occur after the click and in the background. Therefore, responsiveness is immediately restored to the user interface.

  • When you close an item, the clipboard is cleared unnecessarily. Outlook becomes unresponsive when the clipboard content is retrieved from slow applications or from remote applications such as a Terminal Services session.
  • When you copy lots of items in the same store, it takes a long time. This problem occurs when you have InfoPath installed on your computer.

  • When you run the All Mail Items searches across multiple stores in which a result set can be returned, a blank view is substituted for the result set.
  • When you save an Outlook 2007 message, it takes a long time. This problem occurs when you install InfoPath on your computer.
  • When you share a folder with a delegate, the delegate sees your informational meeting updates as regular updates.
  • When you try to use the PropertyAccessor interface on a Recipient object to determine the Recipient flags, an error is returned.
  • When you update the unread counts, Outlook becomes unresponsive. Additionally, the unread counts have been removed completely on operating systems that do not support per-user Fast User Switching unread counts, such as Windows Vista.
  • When you work in Outlook 2007, and you enable the Show in Groups option, folder switch becomes slow, and a performance decrease occurs.
