autodiscover.msn.com certificate problem

Started getting this a couple of days ago, assume it is coming from my .msn email account when outlook checks for mail? Any guess's what might be causing this. Tx..

I'm having an identical problem with this same message when I open Outlook 2010- autodiscover.msn.com 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.

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 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.

Same thing started to happen to me a few days ago. (W10, defender, Office365 home)

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.
