(VB.NET UWP/WinRT) IMAP Move Messages to another Mailbox

Demonstrates how to move emails from one mailbox to another (on the same IMAP server in the same session). This example requires an IMAP server that supports the MOVE extension. (Most IMAP servers support the MOVE extension.)

Note: This example requires Chilkat v9.5.0.64 or later.

Note: The Apple iCloud IMAP server (imap.mail.me.com) does not support the MOVE extension.
