Office 365 - Exchange Error

Hi,

I am using an Apple Mac - with Outlook 2016 and getting the following error when I log into Outlook.

Verify Certificate

A secure connection cannot be established with the server xxxx.xx.xx because its intermediate or root certificate cannot be found.
Do you want to continue.

If you continue, the information that you view and send will be encrypted, but will not be secure.

There is an option to always trust. But this does not seem the best way of fix it.

So how can I resolve this issue so the dialog does not appear.

Thanks,

Ward.

You may have expired Certs in the keychain that need to be cleared out and updated.

Hi,

Thanks for the info. I did configure the email with the automatic options - and it did then connect to exchange. So should I be overriding these settings?

I have attached the specific error - as the article you said talks about a different certificate to the one I am getting.

Maybee I am misunderstanding the steps.

Thanks,

Ward
