    Hello,

    That error 0x800CCC6f almost always happens when your outgoing mail server rejects the message. Usually this means your email account settings just need outgoing server authentication enabled but it can also trigger if you are trying to send a really large attachment or if your antivirus is stepping in.

    Who provides your email account? Tell me so I can check with you your exact server settings and figure out why it is getting blocked.
