Most email services have default settings to filter out spam and junk and return such emails to the sender. Not only can they be a nuisance in your inbox, but with spammers getting more and more sophisticated and creative with their tactics, it is very important to address this evolving threat. Microsoft Office 365 Email Security Outbound Spam PoliciesĪ business email system without spam filtering is highly vulnerable if not unusable. If you don’t, implement them! You will make big improvements your Office 365 email security and reduce the chance your business is compromised by a hacker in the process.Īll these settings are applicable to E3 Level 1 unless indicated otherwise. So if you are an existing user/admin, go back to your settings and verify that you have these controls in place. I’ll also note what Microsoft license that setting requires, and make note of issues that may crop up when implementing them. I’m going to run through each of Office 365’s email settings and explain what the most secure option is. While security should be standard, Microsoft unfortunately gates many settings behind more expensive licenses, leaving smaller businesses more vulnerable. So… after getting a degree in Microsoft licensing (I’m totally kidding, but you wished there was such a course, didn’t you?), I dug deeper into Microsoft Office 365 email security features that each of the licenses offer.
If you think that is confusing, wait till you see the licensing model…
People refer to it as both those terms and shorthand as M365 and O365. There’s lots of configuration on your end to maximize your Microsoft Office 365 email securityīefore I dive deeper, Microsoft 365 was formerly known as Office 365. Microsoft has been improving its security features but its default settings are frankly terrible. The cloud email application for Office 365 users has always been a breeding ground for phishing, malware and very targeted data breaches. Once a hacker has bypassed your email, it’s easy for them to steal sensitive data like Personally Identifiable Information (PII), Protected Health Information (PHI) and even intellectual property. It is the easiest way for bad guys to spread ransomware, spyware, worms, different types of malware, social engineering attacks and other cyber threats. Frankly, their default settings are horrible!Įmail security is important because it is the most common attack vector for attackers looking to gain entry into an enterprise network. The bad guys will walk right in! Unfortunately, Microsoft Office 365 email security leaves much to be desired.
An email server with weak security settings is like a castle without a wall.
