What to check first for Outlook
For Outlook, start by separating outlook.office.com public reachability, web client sign-in, and message send path. A reachable outlook.office.com does not prove every Outlook workflow is healthy.
- Confirm outlook.office.com reachability and compare it with Official website.
- Test web client sign-in and message send path before changing account, device, or DNS settings.
- If you see outlook: messages stay pending, keep the timestamp, final URL, and failing action for support or incident review.
Official Outlook sources
Use these provider-controlled or provider-owned sources after the live check, especially when the verdict is mixed or the issue only affects one workflow.
Official website
Confirms whether the primary outlook.office.com web surface is reachable outside the WebsiteDown.org probe.
Microsoft 365 Service Status
Official Microsoft 365 service health page.
Azure Status
Official Azure public status dashboard.
MSFT365Status
Official updates for Microsoft 365 incidents.
Official Outlook Social Profiles for Live Updates
These are provider-controlled channels from the source list above. They are useful during incidents, but they can still lag behind live reachability symptoms.
Common Outlook outage signs
These patterns help distinguish full outlook.office.com downtime from partial service degradation, account problems, or route-specific failures.
When Outlook only fails for you
Use these steps when WebsiteDown.org or official sources suggest Outlook is generally reachable, but your own session still fails.
- Run the live check, then test send and receive separately with one contact or workspace.
- Switch between web, mobile, Wi-Fi, and mobile data to isolate route or device issues.
- Do not repeatedly reinstall or reset accounts until official Outlook signals rule out a provider-side issue.
How to check if Outlook is down
Use this workflow to compare the WebsiteDown.org result with official sources, your own browser, and a second network before changing account or device settings.
How we check Outlook
WebsiteDown.org checks public reachability for outlook.office.com and separates that signal from product-specific symptoms inside Outlook.
The Outlook profile on this page is scoped to outlook.office.com, categorized as Messaging / Email, and grouped under office. It cross-checks related hosts (www.microsoft.com, portal.office.com, status.office.com), uses verification sources such as Official website, Microsoft 365 Service Status, Azure Status, MSFT365Status, and compares nearby diagnostics including Proton Mail, Signal, Messenger, Microsoft Teams so parent, child, and sibling service outages do not get blended together.
- outlook.office.com Public Reachability: Confirms whether outlook.office.com responds from regional probes before you investigate Outlook app-specific symptoms.
- Web Client Sign-in: Tracks the web client sign-in workflow as a separate Outlook signal, useful when the homepage and user reports disagree.
- Message Send Path: Tracks the message send path workflow as a separate Outlook signal, useful when the homepage and user reports disagree.
- Message Receive And Sync Path: Tracks the message receive and sync path workflow as a separate Outlook signal, useful when the homepage and user reports disagree.
- Attachment Upload: Upload paths can fail separately from public browsing, so this helps separate publishing problems from basic Outlook reachability.
Why trust this Outlook check?
WebsiteDown.org keeps the live verdict, official sources, and service profile separate so you can see what is measured and what still needs confirmation.
- The live result is a reachability signal for outlook.office.com from multiple regions, not a claim that every private Outlook workflow is healthy.
- The service profile is built from curated diagnostic fields: checked surfaces, failure modes, related hosts, official sources, and limitations.
- Official Outlook links are shown separately so you can verify provider-controlled status and support information before escalating.
