Applying S/MIME sign/encryption based on email rules
Hi,
on the latest version of Outlook for Windows is it possible to apply S/MIME signature or encryption based on email rules?
For example, create a sending email rule that sign the mail if the recipient matches a specific domain or email address.

Hi AndreaGiacomin ,
To do this, go to the Microsoft Admin portal and create a mail flow rule. Please, check this out: Define mail flow rules to encrypt email messages - Microsoft Purview | Microsoft Docs

you're referring to OME (Office Message Encryption). This is server-side encryption.
My question is about S/MIME, this is end to end encryption. Where the sender need to use his digital certificate, stored on the computer or in a smart card, to sign the message. This operation need to be done on client side, not server side.- Adin_CalkicSteel Contributor
