My otlook is not feching

Check Microsoft Service Health first because the Outlook.com BootResult: network and Failed to fetch message does not by itself distinguish a Microsoft service incident from a browser or network problem. Microsoft directs users who cannot access Outlook.com to the Service Health Status site.^1^

1. Check for an Outlook incident

1. Open the Service Health Status site.
2. Check Outlook.com or Microsoft 365.
3. If the status is not green, wait for Microsoft to restore the service and then reload Outlook. Microsoft’s sign-in guidance specifically recommends waiting when service status is not green.^2^

Third-party outage reports indicated broader Outlook problems around November 12–13, 2026, but Microsoft Service Health is the authoritative status check.

2. Isolate the browser and network

If Service Health shows no incident:

1. Open Outlook in an InPrivate/Incognito window.
2. Temporarily disable ad-blocking extensions—particularly AdBlock or Ublock. Microsoft documents that these extensions can cause Outlook.com loading problems.^3^
3. Clear only Outlook/Microsoft site data:
   • Open the browser’s Settings.
   • Search Settings for site data or cookies.
   • Remove stored data for outlook.com, live.com, and microsoftonline.com.
   • Close all browser windows, reopen the browser, and sign in again.
4. Use the latest version of a supported browser:
   • Windows: Edge, Firefox, or Chrome
   • macOS: Edge, Safari 16 or later, Firefox, or Chrome
   • Linux: Firefox or Chrome^3^
5. Test the same mailbox on another device and network, such as a phone using mobile data rather than the same Wi-Fi.

Then run a separate comparison: test another Outlook.com mailbox on the original device.

• Same mailbox fails everywhere, but another mailbox works: likely mailbox/account-side; escalate to Microsoft.
• Both mailboxes fail only on the original device or network: focus on that browser, VPN, proxy, firewall, DNS, or network.
• Same mailbox works on mobile data but not Wi-Fi: the original network path is implicated.

3. Contact Microsoft if the mailbox still will not open

If Outlook loads far enough, select Help on its menu bar, enter the problem, then scroll to Still need help? and select Yes.^4^

If Outlook cannot open—or you cannot reach its Help menu—use Microsoft’s direct support route. Include:

• UTC timestamp
• Client ID and Session ID
• BootResult: network
• esrc: StartupData
• TypeError: Failed to fetch
• Results from the two controlled tests above
• Whether Microsoft Service Health showed an incident

Do not post the session or client identifiers publicly beyond a Microsoft support case.
