About Outlook outages
Outlook covers three different things that people report interchangeably: The consumer webmail at outlook.com, Exchange Online mailboxes for business tenants, and the desktop application. They fail independently and the distinction matters when you are trying to work out whether the problem is yours.
A consumer Outlook.com outage looks like a sign-in loop or a mailbox that loads without messages. An Exchange Online incident produces mail delivery delays measured in minutes to hours, with the web client working fine. The desktop client adds its own failure surface - A corrupt OST file, a stuck send-receive, or an add-in crash will show "Disconnected" regardless of service health. Testing outlook.com in a private browser window separates service problems from client problems in about thirty seconds, and Microsoft's status page confirms only tenant-wide and service-wide events.
What to do if Outlook is not working for you
Is it them or you?
Our last check reached outlook.com normally, from a different network, resolver and route than yours. If it is broken for you, the fault is most likely local or too narrow for a single probe to see. Run the check again now to confirm.
The first thing worth trying
Check whether sign-in itself is the problem. If one product fails, it is that product. If you are being asked to sign in again everywhere, the identity layer is the fault and everything will return together.
How work & productivity services typically fail
The desktop app keeps working while the web version fails, or the reverse. Mail appears to send and sits in the outbox. Meeting links fail to join while the calendar entry is perfectly visible. The rest of the steps, and why this category breaks the way it does, are on our work & productivity status page, with more background in what downtime actually costs.
Outlook measured against its peers
How it compares with other work & productivity services
Over the last 30 days Outlook ranks 4 of 11 work & productivity services we monitor, measured on recorded uptime. The category averages 100.0%, and Outlook sits at 100.0%. The steadiest in this group is Google Search.
On speed, Outlook answers our checks in about 717 ms against a category average of 422 ms - Slower than its peers. Response time is not availability, but a service drifting well above its own normal is often the first sign of trouble.
What the last 24 checks looked like
Across the most recent 24 checks, the quickest response was 358 ms and the slowest 2004 ms, against a 30-day average of 717 ms. The chart above plots each one, so a widening spread is visible before it becomes an outage.
All figures are our own measurements, taken every 20 minutes from one network. What that can and cannot see is set out in the methodology, and every work & productivity service is listed on the category page.

An expired certificate stops browsers loading a site entirely while the server itself stays perfectly healthy, which is why we track it beside the uptime figure. Check it yourself.
Outlook status: Common questions
Is Outlook down right now?
Outlook is up and responding normally. This page is refreshed by an automated check that runs every 20 minutes from an independent network, and by reports from visitors.
Why can I not reach Outlook when you say it is up?
Because an outage can be partial. Our check runs from one network and asks for one page. Your problem may be regional, may affect only the mobile app, or may be local to your connection, DNS resolver or browser cache.
How reliable is Outlook?
Outlook has been reachable for 100.0% of the last 5 days we have measured, with 0 seconds of recorded downtime.
Does Outlook have an official status page?
Yes - Outlook publishes one at https://status.cloud.microsoft/. It is the authoritative source for confirmed incidents, though official pages usually update after user reports have already peaked.
