Disable any AdBlock, uBlock, pop-up blocker, or privacy extension for Outlook.com and reload the page, because Microsoft documents these blockers as a cause of Outlook.com loading slowly or timing out.^1^
Restore web access
- Test a private window
- Open an InPrivate/Incognito window in a current version of Edge, Chrome, Firefox, or Safari.
- Visit Outlook.com and sign in.
- If it opens, the problem is in the normal browser profile—typically an extension, cookie, or cached session.
- Disable blockers for Outlook.com
- Temporarily disable AdBlock, uBlock, pop-up blockers, tracking protection extensions, and similar privacy add-ons.
- Alternatively, add Outlook.com to the extension’s allow list.
- Close all browser windows, reopen the browser, and try again. Microsoft specifically identifies AdBlock and uBlock as potentially preventing Outlook.com from loading.^2^
- Test a different network
- Try the Outlook website from a phone using mobile data rather than the same Wi-Fi.
- If it works on mobile data, investigate the original network’s VPN, proxy, DNS filtering, firewall, or router.
- If it times out there too, continue below.
- Check Microsoft service health
- Microsoft advises checking service status when the Microsoft account itself accepts the sign-in but Outlook.com does not work.
- If Outlook is not shown as healthy, wait for service recovery rather than repeatedly changing the password.^3^
If private browsing, multiple current browsers, and a separate network all time out while the Microsoft account dashboard remains accessible, this points away from one browser profile. Check the Outlook.com known-issues page, then contact Microsoft Support and report: “Personal Outlook.com mailbox times out across browsers and networks, but account.microsoft.com works.” That gives support the information needed to investigate a mailbox-side access problem.^4^
Check whether the account was compromised
The timeout alone does not establish that the account was hacked. Since the account dashboard is accessible:
- Open the Microsoft account Recent activity page.
- Review the last 30 days for unfamiliar successful sign-ins, devices, applications, alias changes, password changes, or security-information changes.
- For an unfamiliar event, expand it and select This wasn’t me or Secure your account.
- Change the password and update security information if suspicious activity is present. Microsoft also allows trusted devices to be removed from Security settings.^5^
If compromise is confirmed, first run a full antivirus scan on the device, then change the password. After mailbox access returns, inspect forwarding, connected accounts, and automatic replies for unauthorized changes.^6^
