Double items in Outlook 2007/2010 tasks list

When I schedule something in my Outlook calendar or a task list, the appear twice in tasks panel. If I delete one, both are deleted! What’s wrong?

This issue can be caused by problems in the ‘to-do bar’. To reset your Outlook to-do bar to the default configuration:

1. Click ‘Start’
2. Click ‘Run’
3. Type: outlook.exe /resettodobar

Outlook will launch with your to-do bar re-configured. You may then close and re-open Outlook normally.

Note: Many users experience this issue after opening an Outlook 2003 or 2007 version PST file in Outlook 2010.

  1. Is there anything else I can do to stop this as I have tried the above and it did not work. The same thing happens with my Calendar reminders

  2. Hi Clive,

    This just happened to someone in our office where task items either doubled up or were listed multiple times.

    The reason was because the [View->Arrange by] was set to categories. So if a task item has multiple categories it will display one line per category.

    To resolve the problem change the [View->Arrange by] to date or anything except categories.

  5. I had this problem and ran the utility scanpst.exe, which is on your drive somewhere (when you installed Outlook). That fixed it.

  6. I have Outlook 2010 and had same problem with PST files from Outlook 2003/2007) – double entries in the task bar each time I create a task or set a flag on an email item.
    Fixed as follows in Win 7:
    Closed Outlook.
    Opened a command window (click Start, enter cmd in search, selected cmd.exe)
    Entered the following command:
    “C:\Program Files\Microsoft Office\Office14\OUTLOOK.EXE” /resettodobar
    Outlook reopened and the task bar was displaying correctly.

  7. In my case, it was an upgrade from outlook 2003 to 2010 in a corp environment. For some reason, when it set up the account, it created a duplicate account, and these tasks and calendar entries were in both. I removed one, (control panel, mail) and suddenly all is well.
