export delegated folder ??

i try export a delegated folder (special folder) but it not show in export list of email , how can export a special folder ??

Using Menu > File > Export, you can only export folders from your email account, or Local Folders. You cannot export Search Folders or Smart Folders that way.

What you can do is go into the folder, select all the messages, and choose Save As.

thanks for reply
