Is Outlook.com down right now?

We check outlook.com from one measurement point when you open this page. This shows what we saw, not a worldwide verdict.

A fresh check of outlook.com runs in your browser. If no result appears, run the check on the start page.

About Outlook.com problems

Outlook.com problems can mean sign-in trouble with a Microsoft account, mail that does not arrive or send, or the mail app not syncing. Sign-in for Outlook.com runs through Microsoft's account pages, so cookie and redirect problems there can block mail even when Outlook.com is up. Microsoft's service health page and its Outlook.com support article are the places to check for known problems.

Official information

Outlook.com official status page (verified )

Our check and Outlook.com's own status page can disagree. We test from one location and read only the homepage response. The provider reports what it knows about its own systems, such as sign-in, apps or single regions. A site can answer our check while one feature is broken, and a regional problem can affect one location but not another.

How this check works

  • One measurement location (single-self-hosted-probe), not a worldwide test.
  • We read only the response headers of the HTTPS homepage; page content and features are not tested.
  • We follow at most 5 HTTPS redirects and check every new address again.
  • The whole check stops after 10 seconds.
  • Results are reused for 60 seconds; this page refreshes its saved check at most every 10 minutes.

Typical Outlook.com problems

An editorial list of typical problems, not based on live user reports.

  • Sign-in keeps looping If the Microsoft account sign-in for Outlook.com keeps reloading, clear cookies for outlook.com, live.com and microsoft.com only and try again. Guide: ERR_TOO_MANY_REDIRECTS
  • Outlook.com shows a server error A server error in Outlook.com on the web is on Microsoft's side, so check Microsoft's service health page before changing settings. Guide: 500 Internal Server Error
  • Outlook.com does not load on this network If Outlook.com times out on one network but works on mobile data, a network filter or firewall is a likely cause. Guide: ERR_CONNECTION_TIMED_OUT
  • Certificate warning on public Wi-Fi A certificate warning when opening Outlook.com on public Wi-Fi can mean the network's login page intercepts the connection, so complete that login first. Guide: NET::ERR_CERT_AUTHORITY_INVALID
  • Emails not arriving Check the Junk Email folder and your inbox rules, and check your Microsoft storage, because Outlook.com cannot send or receive email while that storage is full.
  • Mail app does not sync If a phone or desktop mail app stops syncing Outlook.com, remove and re-add the account so it signs in again with current settings.

General fixes: Email

  1. Search spam and filters first Missing messages can end up in spam, junk or a filter folder. Search the whole mailbox for the sender's address before you assume mail is lost.
  2. Check your storage A full mailbox or account storage stops new mail from arriving. The storage overview in your account settings shows how much space is left.
  3. Compare the website and the app Open your mail in a web browser and in the mail app. If only the app fails, remove the account from that app and add it again.
  4. Wait before you resend If a message seems stuck, wait a few minutes before sending it again, so the recipient does not get copies when the service recovers.
