S/MIME
Secure/Multipurpose Internet Mail Extensions (S/MIME) is
an industry standard that encrypts and digitally signs emails to ensure their
integrity and security:
- Encryption: Protects the contents of emails
- Digital signatures: Verifies the sender's identity
- Message integrity: Ensures the email's contents are not altered
- Non-repudiation: Provides a way to prove the origin of the email
- Authentication: Verifies the identities of both the sender and recipient
S/MIME is compatible with most enterprise email clients,
including Outlook for iOS and Android. To add or remove a digital signature
from a message in Outlook on the web, you can:
- Go to the top of the message
- Select More options > Message options
- Select or deselect Digitally sign this message (S/MIME)
