Outlook not responding

Question

Outlook won't open. Outlook will not respond on my iPhone 17e nor on my computers. Just started happening today.

Answer 1

Unfortunately that's likely related to the service-side issues - you can monitor the latest updates via https://status.cloud.microsoft/

Here is the latest available information:

The next update is scheduled for Friday, November 13, 2026, at 5:30 AM (GMT+7).

Answer 2

A widespread Outlook/Microsoft 365 service incident is affecting access today, November 12, 2026, so monitor Microsoft’s service status and retry after the incident is marked resolved rather than reinstalling Outlook on each device.^1^

What to do now

1. Open the Microsoft service status page.
2. Expand Microsoft consumer products, then check Outlook.com.
3. If an incident appears, wait for Service restored, then close and reopen Outlook on the iPhone and computers. Microsoft recommends checking this status page when Outlook.com cannot be accessed.^2^
4. Retry periodically. There is no confirmed universal restoration time in the available incident reporting.

Because the failure began simultaneously on your iPhone and computers, avoid deleting accounts, changing passwords, or reinstalling the apps while the incident remains active. Those actions will not repair a Microsoft-side outage and could add account setup problems afterward.

If the status becomes healthy but Outlook still fails

Try one new isolation test:

• Connect one computer to a different Internet connection, such as a phone hotspot, and open Outlook.com in a browser.
• If it works there, investigate the original Wi-Fi/router or Internet connection.
• If it fails on a different connection after Microsoft reports service restoration, use Outlook.com → Help, enter the problem, and select Still need help? → Yes to contact Outlook.com support.^2^

For a work or school Microsoft 365 account, an administrator can also open Microsoft 365 admin center → Health → Service health → Exchange Online to see tenant-specific incident details and updates.^3^
