This may be a little niche but I found the answer and thought it worth sharing.
I needed to see the date and time that an Outlook calendar item was created (related to a duplicate entry and wanting to keep the first one) and the online solutions talked of advanced properties but didn’t help.
In the end I found this way, which worked for us:
- Make sure that the Developer tab is visible (customise the ribbon to add if not)
- Open the appointment
- From the Developer tab, choose ‘Design this form’
- Choose the ‘All fields’ tab and select ‘Date/Time fields’ from the dropdown list
- This will show some fields including ‘Created’ and give the information you need
If you needed this more generally you can customise the browse list of calendar items, but this works as a one off.
