Whenever I attempt to compact a folder I have created, the following error
message is displayed:

The folder is currrently in use by Outlook Express or by another application.

Outlook Express is able to compact the other folders without displaying an
error message.

I have restarted the computer several times and cleared the Temporary
Internet Files.

I would appreciate any suggestions you have in being able to compact this
folder without receiving an error message.

Thank you.
