Outlook 2016 security warning asking for credentials
Starting last Thursday all my users with Office 2016 pro starting getting a security warning when opening attachments. It won't take their user name or password but they cancel it and all works fine until they close outlook and start it again. I installed on three new laptops all have the same problem. Then a user I installed 6 month ago started having the same issue. We do have our own exchange server 2013 and Certificate is issue through Network Solutions and has not expired. Anyone else having this issue or heard of it?
Attached is screen shot from user.

Hi Chris,
You have only this credential propt when you tried open attachment?
And if they introduce the user and password, selecting "remember my credentials", they continue to have the same message?

The first time we open Outlook, we tried to open any attachment .xlsx or pdf this message pops up. If we enter our username and password it comes back right away. If we cancel it everything works fine until we close Outlook. Then it starts all over again if we open Outlook.

I just tried to login and check the bindings. I couldn't get in by remote desktop. So I've issue a command to restart the start. Let see if the error is still there tomorrow morning when the user start to work again.
Hi Chris,
Ok perfect. Maybe the issue is solved tomorrow.
