    Do you use EMET security?...this kind of warning appears when using that app.

    I note yours is issued by DigiCert Cloud Services CA-1.

    I'm having an identical problem with this same message when I open Outlook 2010- certificate problem.
    Just started a few days ago too.
    I did countless Google searches and could find no solutions that weren't complicated and they dealt with exchange servers. Yours is the only hit I could find with same issue. I'm a home user with only my msn e-mail account in Outlook.

    I am using MS Windows Defender and Malwarebytes Premium 3.1.2. I use SuperAntiSpyware on occasion. It is not enabled by default but enable it once in a while for weekly maintenance. Might add that I am on Win 10 Pro CU and using Outlook 2013.

    I don't use EMET. I have Norton Security on Windows 7 64 bit,with correct firewall settings and no alerts for Outlook- the screenshot meebers posted is solely an Outlook security warning and I suspect an error on Microsoft's part in not updating or renewing certificate names of .msn e-mail accounts.

    I started a thread on Microsoft forums for whatever good it will do. Responses from Microsoft moderator not helpful "we suggest that you contact your IP/Admin/email provider directly to check the settings on their end."- provider is Microsoft not any third party provider.
