I am currently running Exchange 2007, I have a few mail enabled Public Folders, WhenI was running exchange 2003 I Could from Outlook(2007 and 2000) just select a public folder then run the archive utility to archive the folder according to the archive criteriaI selected. Now whenI try it I get "The selected folder can not be archived" I am the owner of the public folder. I have also attempted to do it as the administrator account whom has all exchange admin rights. I get the same results. Any ideas ?

I've read about this issue before. not a fix, but a work-around could be to use the export function instead. just delete afterwards.
