Group email issue Windows Live Mail


  • Help needed please

    I am now unable to send a group emails after the recommended Windows Live Mail upgrade using the IMAP settings.

    The following error message appears

    An unknown error has occurred.


    Subject 'Group message'

    Server Error: 550

    Server Response: 550 5.3.4 Requested action not taken; Mail delivery to EXO failed.

    Server: ''

    Windows Live Mail Error ID: 0x800CCC69

    Protocol: SMTP

    Port: 587

    I'm also getting the error message:-


    There was an error when attempting to connect to the Windows Live Calendar service. If the error persists, check to see if there's an upgrade of Windows Live Mail available or contact a service representative.

    Computer is being run on Windows 7.

    NB All outgoing messages have been deleted from Outlook folder and I can send emails to individuals.
