Unfortunately that's likely due to the ongoing service-side outage. You can monitor the latest updates via https://status.cloud.microsoft/

Here is the latest available information:

The current failure coincides with Microsoft’s November 12, 2026 service degradation, so stop device-level troubleshooting and wait until the public service-status page reports recovery before trying Outlook.com again.^1^

What to do now

Monitor Service Health Status for Microsoft 365 and Outlook availability.^1^
Once the incident is shown as resolved, wait several minutes and attempt one fresh Outlook.com sign-in.
If necessary, use a private/InPrivate browser window only for that post-recovery test, so an existing failed session is not reused.

The BootResult: network, Failed to fetch, and StartupData entries indicate that Outlook Web could not retrieve the data required to start. Because the same account fails across all your devices during a reported service degradation, reinstalling applications, resetting devices, or repeatedly changing passwords is not an appropriate next step.

Microsoft’s Outlook.com known-issues guidance also directs users who cannot access Outlook.com to the public service-status page.^2^

If it still fails after Microsoft reports recovery

If the status page is healthy but the mailbox continues producing the same error across multiple devices and networks:

Go to the Microsoft Support contact page: https://support.microsoft.com/en-us/home/contact
Select Get Home Support.
Enter Outlook.com or Hotmail.
Select Contact support.
Provide:
- The UTC timestamp
- Client ID and Session ID
- BootResult: network
- esrc: StartupData
- TypeError: Failed to fetch
- Confirmation that it occurs on multiple devices

This route is the documented fallback used for persistent Outlook.com startup failures that require account or mailbox investigation.^3^

Do not post new Client IDs or Session IDs publicly; provide them only through Microsoft’s support channel.
