Microsoft 365 Outage Plan for Small Businesses (5 Steps)

When Outlook and Teams go down at the same time, most companies lose the way they talk to each other. Here is a simple plan.

1. Confirm it's Microsoft

Check before anyone starts rebooting routers.

admin.microsoft.com > Health > Service health

2. Pick an outage channel

A text group or phone tree that does not depend on Microsoft. Decide it now, not during the outage.

3. Keep numbers offline

Print or save staff and key customer phone numbers outside Outlook.

4. Don't touch DNS or MX

Changing mail records during a provider outage usually makes recovery slower and can bounce mail.

5. Review afterwards

Write down what stopped working and what people used instead, then update the plan.

FAQ

Should we switch email providers?

Every provider has outages. A plan for working through one matters more than the logo.

Does Microsoft give credits for outages?

Business plans have a service level agreement. Ask your admin or reseller about filing a claim.
