    Hi Prussic,

    It sounds like the sending server requires SSL but you don't have SSL checked in your settings.

    Also double check that you are using the correct port, most likely 465 or 587, not 25.

    Prussic,

    According to the PSU Help Desk the problem occurred with recent Windows update. They said they are working on the issue. In the meantime you can use Webmail as a workaround.
