Office Outlook Security Certificate Out of Date.
I keep getting the attached Security Certificate warning on my computer when I open Office Outlook. I have updated the certificate but it hasn't made any difference. How do I get rid of this Security Certificate problem please? Please note I am not using Office 365. I have Office 2016 on my computer. When the certificate warning appears I usually get a request to sign into my email at Microsoft Outlook.com. Any thoughts please?
