How to generate and update the X509 certificate

If you are prompted to update your Identity Provider certificate in the Zoom portal, please refer to the instructions on the Microsoft Support site on how to generate a new certificate in ADFS. Once you have the new certificate, edit the SSO configuration on the Zoom portal and replace the existing certificate with the newly generated version.
