When Outlook Goes Down, Can Your Organization Keep Running?

Thursday’s Outlook Outage Was a Continuity Test. How Did You Do?

On Thursday, a lot of organizations lost Outlook and Teams when Microsoft’s Exchange Online service started failing. Fixing it was Microsoft’s job. How your organization got through those hours is the more useful question.

For the schools, local governments, and utilities we work with, email isn’t just email. It’s how work orders get routed, how vendors get paid, how parents hear about a delay, and how an on-call operator finds out something needs attention. When it stops, a lot of other things quietly stop with it.

This is why we keep telling clients that business continuity is not only a ransomware conversation. Most of the disruptions you’ll actually live through look like Thursday. A provider you depend on has a bad day, and it’s out of your hands.

Here are five questions worth asking your team this week while it’s fresh.

1. Who noticed first, and how did everyone else find out? If the answer is “people started texting each other,” that’s your real communication plan. Write it down and make it intentional.
2. Can you reach your staff without Microsoft 365? A notification tool, a text tree, a printed phone list in a drawer. If your emergency contact list lives in Outlook, you couldn’t open it Thursday.
3. Which processes stalled? Approvals, purchase orders, help desk tickets, alarm notifications. Anything that routes through email should have a simple manual fallback.
4. How long can you go without email before it becomes a real problem? An hour is an inconvenience. A full business day might mean a missed bid deadline or a late public notice. That number is your recovery time objective, and most organizations have never actually set it.
5. Did anyone get a fake “log back in to your mailbox” email? Outages are prime time for phishing. When people expect mailbox problems, a message asking them to sign in again looks perfectly normal. A quick reminder to staff now is cheap insurance.

None of this needs a 200 page plan. A business impact analysis tells you which services matter most and how long you can go without them. A short, practical continuity plan tells people what to do when one of them goes down. And a tabletop exercise lets your team practice it once before it counts.

Here’s the uncomfortable part. Thursday was the easy version. Microsoft was working the problem, and everyone knew service would come back. Next time it could be ransomware on your own network, or a vendor that doesn’t come back for a week. That time nobody else is coming to fix it, and the clock is running on you. If your team couldn’t answer those five questions with confidence, you’re not ready for that day.

That’s a conversation to have now, not during the next outage. SecureCyber helps all types of organizations get ready for days like Thursday.
