Outlook not working - getting Hmmm...can't reach this page error

Microsoft currently reports a Microsoft 365 Business or Enterprise service degradation, so first determine whether that incident affects a work/school mailbox or whether this is a separate Outlook.com password or browser-access problem.^1^

1. Check service status and test browser access

1. Open Microsoft’s Service Health Status page.
2. Check whether Outlook is listed among the affected services:
   • Work or school account: If Outlook is affected, wait for Microsoft to mark the incident resolved before changing the account again.
   • Personal Outlook.com, Hotmail, Live, or MSN account: The displayed degradation is labeled Business or Enterprise, so it does not by itself confirm an Outlook.com outage.
3. Open a private/InPrivate browser window and test both:
   • Microsoft account
   • Outlook.com

Microsoft recommends checking service status when Outlook.com can be reached but is not operating normally.^2^

Since reinstalling did not help, do not reinstall Outlook again. Use the test results below.

2. If neither website loads

This points to the browser, device, or network path rather than an Outlook password.

• Test another browser.
• Test another device on the same network.
• Test the original device on another network, such as a mobile hotspot.
• Temporarily disconnect any VPN or proxy and retry.
• If only the original browser fails, clear its site data for Microsoft sign-in and Outlook pages.
• If every device fails only on the same network, restart the router or contact the network administrator/ISP.

Do not reset the password until a Microsoft sign-in page loads successfully.

3. If the pages load but the password is rejected

For a personal Outlook.com/Hotmail account, recover the Microsoft account password:

1. Open Microsoft’s account recovery guidance.^3^
2. Select Recover your account.
3. Enter the Outlook.com address, phone number, Skype name, or another alias associated with the account.
4. Choose where to receive the security code and select Next.
5. Select Send code, enter it under Verify your identity, and select Next.
6. Enter and confirm a new password.
7. Test that password first at Microsoft account, then at Outlook.com.

Check the complete email domain carefully—for example, .com versus .co.uk. If the email address is not recognized, try another alias or phone number connected to the account.^3^

If recovery still fails, use Microsoft’s sign-in helper; Outlook.com support cannot manually grant access to an account with a sign-in problem.^4^

For a work or school account, contact the organization’s Microsoft 365 administrator rather than using personal-account recovery. The administrator can check Microsoft 365 admin center → Health → Service health for tenant-specific incidents.^5^

4. If browser sign-in works but the Outlook app still fails

The account and password are working; the remaining problem is specific to the installed client or its saved account information. The correct removal or profile-recreation procedure depends on whether this is new Outlook for Windows, classic Outlook, Outlook for Mac, iPhone, or Android. Do not attempt another reinstall or delete an Outlook profile until the platform is identified, because profile removal can affect locally stored data.
