Public Folder column labels

Hi all,

We're using Exchange 5.5 and Outlook 2000. I'm trying (and yes, I have the proper permissions set for my updating the folder contents, etc.) to change the column label name for a public folder that is using custom fields, but even though it allows me to make the change, when we log off and then back onto the folder it reverts to it's original name.

Any suggestions, or am I missing something?
