    1. Hello ictatty & David,

      Thank you for contacting us. I definitely understand your concerns, as this is a big deal to us as well. We are currently still investigating and this issue, and working towards a solution.

      Essentially, Microsoft pushed out this update to some versions of Outlook, to address a security vulnerability. So, right now some versions of Outlook are not working with SSL connections due to a security risk.

      We will post updated information as soon as possible.

      You can use other email clients with SSL in the meantime, such as Thunderbird, or Webmail.

      Thank you for your patience,
