message forwarding

Message forwarding in Windows Live Mail can be blocked by ISP spam filters, causing error messages that prevent sending any outgoing messages. Users may find that a forwarded message flagged as spam becomes stuck, blocking all new outgoing mail. The stuck message may not appear in any visible folder, making it difficult to delete. This issue highlights how message forwarding can trigger spam detection and disrupt email functionality. Troubleshooting involves locating and removing the problematic forwarded message, often requiring workarounds like clearing the outbox or adjusting spam filter settings.
