Initially after upgrading from 2000 to 2007 outlook seemed to work properly.
Some time later I tried using the on-line tutorial and I think this is where
the troubles started. (I may have used the tutorial with Outlook open but I'm
not sure)

Indications:
When I start Outlook, immediately after the Outlook logo comes up, a
dialogue box headed Microsoft LDAP Directory comes up with one tab labled
Connection details and the following:
Server name: NULL
Port: 3286
User name: NULL
Password: (this is blank)
The Secure Password Authentication box is unchecked.

Pressing OK, Cancel, or exiting makes the box go away and Outlook starts to
open. Before opening is complete a pop-up from the Outlook symbol on the task
bar bears the message: "There was a problem reading one or more of your
reminders. Some reminders may not appear"

Exiting the pop-up Outlook appears normal with the Calendar and iminent
appointments shown in the To-Do pane but in the pane where the tasks should
be there is a message "The operation failed. An object could not be found"
In addition there is no reminder of appointments and they seem to clear
themselves on expiry,

I've tried uninstalling, reinstalling and detect and repair to no avail.

I've raised this issue previously (26th March) with no response except that
today (21st May) Owensnig has said he is experiencing a similar difficulty.

Who's the star on this one?
