Property Value

A String value indicating the current selected folder name.

Remarks

By default, the "INBOX" will be seleted automatically when the client connects to the IMAP4/Exchange server, then you can get, copy, delete the emails in selected folder. To manipulate emails in specific folder, please use MailClient.SelectFolder method to select the folder at first. POP3 protocol doesn't support this feature.
