" Receiving' reported error (0x800CCC0F) :  'The connection to the server was interrupted. If this problem  continues, contact your server administrator or Internet service  provider (ISP).  The server responded: -ERR Can not connect to e-mail  server. Error:100502" 

The problem is that it not gives this error always. sometime it works fine and somtime it block with this error.

    The issue seems to be occur only at Outlook as it is a client-side issue whereas you need to ensure below things on settings.

    1: Ensure that your PC is connected to the Internet
    2: Check e-mail account settings in Outlook.
    3. antivirus or firewall blocking
    4. Check and delete spam mails if any.
