S/MIME is used to support enhanced encryption in transit, and automatically encrypts your outgoing emails if it can.
Important: These steps only work if you have S/MIME enabled on your account.
1. Start composing a message.
2. Add recipients to the "To" field.
3. To the right of your recipients, you'll see a lock icon that shows the level of encryption that is supported by your message's recipients. If there are multiple users with various encryption levels, the icon will show the lowest encryption status.
4. To change your S/MIME settings or learn more about your recipient's level of encryption, click the lock, then View details.
1. Open a message.
2. On an Android device: Tap View details View security details.
On an iPhone or iPad: Tap View details.
3. You'll see a colored lock icon that shows you what level of encryption was used to send the message.
When you're sending or receiving messages, you can see the level of encryption a message has. The color of the icon will change based on the level of encryption.
• Green (S/MIME enhanced encryption) . Suitable for your most sensitive information. S/MIME encrypts all outgoing messages if we have the recipient's public key. Only the recipient with the corresponding private key can decrypt this message.
• Gray (TLS - standard encryption) . Suitable for most messages. TLS (Transport Layer Security) is used for messages exchanged with other email services who don't support S/MIME.
• Tip: TLS support is not guaranteed. Support is inferred from past communications with the email service.
If you're writing a message and see the red lock icon, consider removing these addresses or deleting the confidential information. To see which address is unencrypted, click View Details.
If you received a message with the red lock icon and the message contained particularly sensitive content, let the sender know and they can contact their email service provider.
