Hi,

if you want to use email encryption, like S/MIME, either via OWA or Outlook, you would need to get certificate, preferable public one. You would also need to configure email, so that it is send encrypted, since that does not happened automatically.

How to turn in in OWA, and more about that topic, you can read at following link: https://blogs.technet.microsoft.com/exchange/2007/08/20/secure-messaging-with-smime-and-owa-on-exchange-server-2007-sp1/

As for PGP, I think you need some 3rd party app for that, but not quite sure.

Regards,
Ivan.

PGP can be 3rd party plugin to you Spam Filtering Solution. S/MIME as per above comment from Ivan.
Best to check with the Exchange Admin, he probably has the information documented from server build implementation :)

If you don't know then you probably are NOT using any form of encryption.  S/Mme requires a certificate for all recipients and senders in a message and uses PKI ( public key infrastructure)  The sender encrypts with their private key and the recipients public key.. The recipient decrypts using their private key and the senders public key. This means the previously you have exchanged keys.  The easiest way is to simply sign a message and the recipient can then import that key into their certificate store.

Email by design is not secure nor is delivery guaranteed.
