How to Prepare Your Business for a Microsoft 365 Outage

Getting your Trinity Audio player ready...

Most businesses rely heavily on the cloud. Email, files, accounting, bookings, payments, and other everyday tools are often online. When one of those services suddenly goes down, employees may not be able to send emails, access documents, process payments, or keep normal operations moving.

And it doesn’t take a cyberattack to cause that kind of disruption. In July 2024, a faulty software update from cybersecurity company CrowdStrike caused millions of Windows computers around the world to crash within hours. Microsoft estimated that the outage affected 8.5 million Windows devices, disrupting airlines, banks, hospitals, and businesses worldwide.

Even Major Cloud Services Experience Outages

Microsoft 365 has experienced outages that left businesses without access to email, Teams, and other essential services for hours. Internet providers can experience disruptions too, and when your connection goes down, many of the cloud tools your business depends on can become unreachable.

Today’s businesses often rely on just a handful of online platforms to handle critical tasks. If one of those platforms becomes unavailable, the work connected to it can stop until service is restored. Choosing a large, well-known provider doesn’t eliminate the possibility of downtime.

How Downtime Can Disrupt Your Business

When an essential service goes offline, the impact can spread quickly. Employees may lose access to email and files, while an unavailable payment or booking system can prevent customers from making purchases or scheduling appointments. Communication can become difficult, and employees may be left waiting for systems to come back online.

With a widespread provider outage, there’s usually very little your business can do to restore the service itself. That’s why an outage plan isn’t about fixing Microsoft’s systems. It’s about keeping your business operating and your customers informed while you wait for service to return.

What Your Business Outage Plan Should Include

A practical outage plan should answer a few important questions:

• Which systems are essential? Identify the services that would seriously disrupt your business if they became unavailable, such as email, payment processing, file storage, or booking software. Focus on the systems that would actually prevent employees from doing their jobs.
• How will everyone communicate? Have another way for employees to stay in touch if your primary communication platform isn’t working. Phone calls, text messages, or a group chat on a separate platform can provide a simple backup.
• What information should be available offline? Keep essential information, such as customer contacts, important phone numbers, and critical documents, somewhere you can access without relying on your main cloud services. This could be a printed copy or information stored securely on a device.
• Who takes the lead? Decide who will make decisions during an outage and who will communicate updates to employees and customers. Clear responsibilities help prevent confusion when systems are unavailable.
• Where do you check for updates, and who do you contact? Know where to find the provider’s official service status page and how to contact your IT provider if you need help determining what’s happening.

Steps to Take When a Service Goes Down

1. Determine whether the problem is widespread. Check the provider’s official status page or find out whether other users are experiencing the same issue. If it’s a confirmed service outage, repeatedly restarting devices or changing settings probably won’t solve the problem.

2. Update your team. Tell employees what’s unavailable and what they should use instead. A quick update can prevent everyone from spending time troubleshooting the same issue individually.

3. Move to your backup communication method. Switch to phone calls, text messages, or another approved platform so employees can continue coordinating while the main service is unavailable.

4. Keep customers informed when necessary. If the outage affects bookings, payments, customer support, or another customer-facing service, explain what’s happening and let customers know when they should check back.

5. Record the basic details. Note when the outage started, which systems were affected, and any problems it caused. A short record can help your business review the incident afterward and identify areas where the outage plan could improve.

Simple Ways to Reduce the Impact of an Outage

• Make important files accessible offline. OneDrive and SharePoint can be configured so certain files are available on a device even when cloud access is interrupted. Ask your IT provider to confirm that important files are available where they’re needed.
• Have another way to connect to the internet. If your primary internet connection goes down, a mobile hotspot may allow essential employees to temporarily get back online.
• Bookmark important status pages. Save the official status pages for Microsoft 365 and other critical services. These can quickly help you determine whether the problem is with your business or the provider.
• Keep essential contacts accessible. Important phone numbers and contact information shouldn’t exist only in a cloud platform. Keep a secure offline copy or store critical contacts directly on an approved device.
• Ask your IT provider about outage alerts. Your IT provider may be able to monitor important services and alert you to known outages, helping your team respond before employees or customers begin reporting problems.

Create a One-Page Outage Plan

Your business continuity plan for cloud outages doesn’t need to be complicated. Keep it to one page and store it somewhere employees can access even if your primary systems are unavailable.

Include your critical services, backup communication method, location of essential offline information, the person responsible for managing the response, and your IT support contact. Review the plan once or twice a year to make sure names, phone numbers, systems, and procedures are still accurate.

A little preparation can make a major difference when Microsoft 365 or another cloud service goes offline. You may not be able to prevent an outage, but you can make sure your business knows what to do when one happens. To learn more, contact Twintel today.
