Sent Items Not Saved In Express Within the MailSite Express email client, users report that when selecting the "Save copy of outgoing message" options, emails are not being saved to the "Sent Items" folder. This is due to a permissions issue on the Cache & temp directories within the MailSite Directory. To solve this problem assign the "everyone" account with full permissions to the "cache" and "temp" directories within the MailSite directory. To clairfy, it is the NT account used for the Express virtual directory (or website) in IIS that requires the permissions on these directories.
