How to delete locations from the location history when creating a new appointment in Outlook?

Question

When I create a new appointment in Outlook the "Location" box shows me a history of all the locations I typed before. Some entires are the result of typos or are just obsolete.

How do I delete specific entries from this list or clear even the whole list?

Answer 1

Slipstick (a great reference on all things Outlook) has an explanation on how to clean the whole list. Apparently there is no way to remove specific entries:

To clear the Location drop-down list on Outlook appointments

Outlook appointments show a drop-down list for Location, populated with the most recently used locations added to appointments. You cannot populate this list with your own preferred locations. You can, however, clear the list by closing Outlook, removing a value in the Windows registry and then restarting Outlook. Always make a backup of the registry before making any changes.

For Outlook 2000, the value to remove is:

HKEY_USERS\.DEFAULT\Software\Microsoft\Office\9.0\Outlook\Preferences\LocationMRU

Outlook will automatically add the value back into the registry the next time you set a location on an appointment.

In Outlook 2002, 2003, and 2007, the value is found at:

HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Preferences\LocationMRU

Replace the xx with 12 when using Outlook 2007, 11 when using Outlook 2003, or 10 when using Outlook 2002.
