IMAP folders not visible in Expess

MailSite Express users cannot see the IMAP folders created in their account.

Delete the fldsum.imp file, located at $\BOX\(username)\fldsum.imp.

Then have the user log out and back into their account. This triggers the IMAP server to relist the folders. If this works, delete the fldsum.imp file for all the affected accounts, or perform a windows search for fldsum.imp and delete the results. This will delete the files globally for all users.
