We’ve already showed you how to sign, encrypt and decrypt e-mails in Thunderbird e-mail client, now it’s time for the same in Outlook. Read our article or watch the instructional video showing every step that we made for you.
When you are operating with e-mails in your everyday life, you’re most likely to use these three security features cryptography keys are used for:

First of all, we’re going to set up GpgOL really quickly so it behaves the way we want it to. We’re going to look into General and Automation settings.

By checking “signing and encrypting new messages by default” in the General settings you won’t need to do it manually before sending the email – this way, you’ll never send a message without signature and encryption by mistake.
If you don’t your emails to be signed and encrypted automatically, you can leave those options unchecked, we will show you how to do these actions manually in following paragraphs.
By unchecking everything in the Automation settings, you’re making sure you’re sending the emails with correct keys of the recipient as well as your own – you’ll check it manually yourself. Otherwise, Outlook will choose the keys on its own which may be a problem if you have old, revoked keys in your key manager.
If you don’t choose to have your e-mails signed and/or encrypted automatically, you can, of course, do it manually each time while you’re composing the message.
There’s a button with the symbol of Lock on it at the top right corner of the window with the symbol of Lock on it. If you click it, it will both sign and encrypt the e-mail.
If you want to do only one of these actions, click the button saying Secure underneath the Lock symbol, it will show you options Sign and Encrypt. Choose whichever you want to.

You’re going to need Cryptoucan for this operation since you’re signing the message with your private key.
To check signatures on messages:

You don’t need Cryptoucan for this operation since you’re using public key of the person you’re send the message to.

You need your Cryptoucan once again since you are decrypting the e-mail with your private key.
