signing in to my email using outlook

When I log in to my email using Outlook, for the last several days, I keep getting this message:

The server you are connected to is using a security certificate that cannot be verified. The target principle name is incorrect.

Do you want to continue using this server?

Hello, ken4u2. Thank you for joining the Xfinity forums community! Please remember that using third-party email clients (e.g., Outlook, Apple Mail, Thunderbird, etc.) to access your Comcast.net email address can potentially expose your Xfinity ID and password to fraud and other risks. We recommend you access your Comcast email by going to Xfinity Connect. We do have some helpful information that should help you to reconfigure your comcast.net email in Outlook, found here.

Thanks ThomasA for your prompt reply, and for the link to the directions for reconfiguring my Outlook email. This will hopefully change the warning for the invalid certificate every time I use Outlook to log in to my Xfinity email account.
