How to configure classification in email notification using MSGraph option

Hi Team, how to configuration the classification using email notification using MSGraph option. Successfully able to send the option. however, want to add classification like public, confidential, group use etc. pls suggest if this is possible using email notification.

One of the older forum discussions mentions that Pega does not support adding custom email headers OOTB and this affects things like Sensitivity and Importance.

So if your organization requires classifications like Public or Confidential, you might need a customization that modifies the MS Graph message payload, potentially using MS Graph extended properties such as MAPI sensitivity property, but this would need validation with Microsoft 365 behaviour in your tenant.

Hope this helps
