Removes all messages from mailbox.

None  

object.RemoveAll

The RemoveAll Method syntax has these parts:

RemoveAll method will remove all messages from the mailbox file, or all parts from some message. However, contents of the mailbox will not be updated until you manually call Update method.

If current Message object represents part of another message, then it will remove all parts from that particular message. Same as before - you have to call Update to make actual changes in the mailbox file.

To see the difference,

mailbox.RemoveAll will remove all messages from the mailbox

and

mailbox.Message(0).Parts.RemoveAll will remove all parts from first message.
