Error installing Office 365 account to Outlook 2013: "The name on the security certificate is invalid or does not match the name of the site."

Hi,

I installed an Office 365 acccount into Outlook 2013 and got this message as it was searching for the details before the green ticks:

"The name on the security certificate is invalid or does not match the name of the site."
It still went through correctly and seems to be working fine. Is it anything to worry about?

Thanks!

Are you running a hybrid deployment? This is a symptom of mismatched certificate among CAS servers in Exchange, as well as using self-signed certificates in on-premise Exchange. Please see this from Microsoft, which applies to hybrid deployments.
