Check for IMAP IDLE Mailbox Updates

See more IMAP Examples

Demonstrates the Chilkat Imap.IdleCheck method, which waits for mailbox updates after IdleStart has entered IDLE mode. The only argument is a timeout in milliseconds; 0 performs a non-blocking poll of notifications already received. This example waits up to 30 seconds.

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.
