Email security is no longer something you can afford to take lightly. With more businesses relying on cloud-based platforms like Microsoft 365, the risk of cyber threats has never been higher. While Microsoft 365 offers robust security features, cybercriminals are constantly evolving, and it’s important to stay one step ahead. 

What is Microsoft 365? 

You may remember it as Office 365, but in 2020, Microsoft rebranded its suite of cloud-based services to Microsoft 365, reflecting the expanded features beyond the traditional office tools. Microsoft 365 still offers familiar programs like Word, Excel, and Outlook, but it now also includes advanced security features, cloud storage, and AI-powered tools designed to support businesses. 

But don’t worry—we’re here to help you keep your inbox secure. Here are some ways to enhance your Microsoft 365 email security and a few simple steps you can take to protect your business. 

Multifactor Authentication 

If there’s one step you cannot skip, it’s enabling multifactor authentication (MFA). It’s like locking your front door and then adding a security system for good measure. MFA adds that extra layer of protection. 

Don’t just take our word for it—cyber experts agree that MFA can block over 99% of account hacking attempts. If you’re still using just a password for email access, it’s like leaving the door wide open for cybercriminals. 

Watch Out for Phishing Attacks 

We’ve all been there—an email arrives claiming you’ve won a prize, or there’s an urgent message from “your bank.” These phishing attacks are designed to trick you into clicking malicious links or sharing sensitive information. They can look incredibly convincing, but a closer inspection often reveals a few telltale signs. 

In Microsoft 365, you can set up phishing detection to help filter out these attacks. But here’s a pro tip: always verify before clicking. And, if something feels off, trust your gut. It's better to double-check than fall for a scam that could harm your business.  

Email Encryption 

Encryption sounds complicated, but it’s just a fancy way of saying, “Let’s scramble this message so only the intended recipient can read it.” Microsoft 365 offers built-in encryption options, making protecting sensitive emails, especially those containing financial data, contracts, or personal information easy. 

Regular Updates and Patching 

Yes, updates can be a bit of a hassle—those pop-up reminders can feel like they come at the worst times. However, keeping Microsoft 365 (and all your software) up to date is one of the easiest ways to block cyber threats. Each update usually includes important security patches that fix vulnerabilities, meaning cybercriminals will have fewer entry points. 

Tip: Set your updates to install automatically overnight. That way, you’ll wake up to a safer system without interrupting your workflow.  

Data Loss Prevention (DLP) 

Data Loss Prevention (DLP) tools in Microsoft 365 allow you to create policies that prevent sensitive information from being shared inappropriately, either by accident or by malicious actors. For example, if someone tries to send an email containing social security numbers or credit card details, Microsoft 365 can block it or alert you before the email goes out. 

It’s like having a built-in safety net because, let's face it, even the most well-meaning employee can slip up occasionally.
