I'm using Outlook 2007 and when I create a task it shows on the To Do List 4
times.

My HDD crashed and I had to do a clean OS installation (WinXP Pro SP2). I
installed Office and copied my backup .PST file into \local
settings\application data\Microsoft\Outlook\. Then I opened and activated
Outlook. I changed the data file location to the correct location and PST
file and deleted the new profile which I had created in error when Outlook
activated. Obviously I've messed up somewhere, possibly when backing up the
original PST file.

Is there any way to fix this mess? Nothing else is showing up more than
once, only my Tasks.

TIA
