The use of a digital ID is currently not supported in Outlook for idgard.

When using the idgard add-in, a link to an idgard Box or Data Room is sent, which generally can only be accessed by users with the respective pass code or with the appropriate permissions in the Data Room. At the moment, this message cannot be verified via a certificate.
