How do you unencrypt emails in out look?

To decrypt encrypted emails in Outlook, you typically need the appropriate digital certificate or encryption key associated with the email. When you receive an encrypted email, Outlook should automatically use your private key to decrypt it, provided you have the necessary permissions. If prompted, ensure you enter your passWord or PIN for your certificate. If you encounter issues, check your settings or contact the sender to ensure they used the correct encryption method compatible with your setup.
