Outlook 2007: To Do list missing

[Marco]

In my company we are busy with upgrading from Office 2000 to Office 2007.
When starting Outlook 2007, then Outlook automatically migrates outlook.pst
to the new version. We did that already many times without any problem. Now
my colleque has the problem that the "To-Do list" is missing.

I can click on the "Tasks"-button in the navigation pane. Then I see at the
left under "My Tasks": "To-Do list" (with red flag) and "Tasks". When I click
"Tasks" I get all his tasks in the big window in the middle. When I click
"To-Do list", then I get a big blue window in the middle with the text
"Cannot display the folder". On other computers of other colleques I see in
the window the list with tasks.

The "To-Do list" is also normally seen in a small window at the right when I
click on the "Mail"-button in the navigation pane, but now this small window
is also blue with the text "The operation failed. An object could not be
found."

What could be the problem? And how can I solve this problem?

With kind regards,

Marco.

My colleque has solved the problem by himself. In de "Data file management"
(file-menu) he found "personal maps" twice (tab "data files"). He delete one
of them, restarted Outlook and the problem was solved.
