Microsoft Office 365 security changes: What you need to know

By Anita Glover, Marketing Manager | Published 19 Feb 2024

You may already be aware of some changes Microsoft are making to the security settings within your Office 365 tenant(s), but if not, strap in. ?

What’s happening?

Starting 11 March 2024, security defaults will be implemented by Microsoft on all Office 365 tenants that do not already have Conditional Access policies in place. These defaults will enforce Multi-Factor Authentication (MFA) for all user accounts and stop any ‘legacy authentication’ which is sometimes used by applications to connect to 365.

What’s the impact? 

This change will impact each business differently, for some you may find things like your scanner or your phone system stop being able to send out e-mails, or you may find some of your staff are unable to login until they enable MFA. Enabling MFA means installing Microsoft Authenticator or a similar app on the person’s phone or tablet, even if that is not a company issued device. 

What do you need to do?

The best starting point is for you to ensure your staff are setup for MFA. Yes, we know you’ve heard this a million times, but MFA is the gold standard for securing online accounts. Don’t wait for Microsoft to hit the switch, it’s much easier to manage this rollout in a controlled way in advance.

What are we doing?

If you’re one of our managed services clients, we’ve already assessed your legacy authentication usage and identified any gaps in your MFA rollout. If you are likely to be affected by the changes, your trusty Technical Account Manager (TAM) will be reaching out soon.
