BST, Please could you try a small experiemnt for me.
In outlook, go to the calendar view, click on 31 to view the month.
Find an empty day and double left click in that empty day. That should bring up a blank appointment form
By default the start time will be 08:00 and the end time 08:30, on the day you chose. OK so far?
Just to the right of the start time should be a tick box labelled "All Day Event" If you tick this then the start time and end time fields should disappear from the form. Do they?
If you then type something into the subject field, make sure All Day Event is ticked, then click save and close you should go back to the calendar with just the subject displayed, no time to the left of the subject.
What happens on your system?
Again, find an empty day and right click into it.
Choose Customise Current View, which should open up a form.
The top entry should be Feilds, with start, end to the right.
If not, what does it say?
If it doesn't, go down and click on Reset Current View and see if that puts it right.
