Microsoft’s design is not quite as simple as Google’s, and is different depending on which version you’re using: either the locally installed Outlook application or the web-based Microsoft 365 interface. How do you check for TLS encryption in Outlook?Īs with Google’s Gmail service, you can see if an Outlook message was encrypted by reviewing the email header. If a recipient is using an email service provider that does not support TLS, the encryption is removed and the message is delivered in plain text-making it easy for malicious parties to intercept it. However, even though this means that email sent and received via Outlook can be encrypted, it doesn’t mean email is encrypted. (Paubox supports both TLS 1.2 and 1.3, per NSA guidelines). Microsoft’s email application, Outlook, does support TLS, and in March, Microsoft began requiring TLS version 1.2, and dropping support of TLS 1.0 and 1.1. The Microsoft Office Suite, and its online counterpart Microsoft 365, is the most popular collection of software tools for businesses (though Google’s offering is proving to be a fierce competitor in the cloud space). We’ve covered different ways to check your email setup for TLS support, including checking for TLS encryption in Google’s email services. Email can be intercepted, creating a potential HIPAA violation for covered entities.Įmail can be protected via encryption, most commonly using an industry standard called Transport Layer Security (TLS). Attacks like ransomware are increasingly common.
