Check Microsoft’s Service Health Status first; if Outlook.com is not green, this is a service incident and the supported action is to wait until service returns to normal before signing in again.^1^
Since three browsers produce the same spinning logo and blank page, simply changing browsers again is unlikely to add useful information.
1. Check the live service status
Open the Service Health Status site and look for Outlook.com or Microsoft account sign-in problems. Microsoft directs Outlook.com users there for current access incidents.^2^
- Incident displayed: Wait for Microsoft to mark it resolved, then retry.
- Everything green: Continue below; no confirmed widespread outage is established from the symptoms alone.
2. Reset the Microsoft sign-in session
Clear site data/cookies specifically for Microsoft and Outlook sites, rather than changing browsers again:
- Close every Outlook, Hotmail, and Microsoft account tab.
- In one browser, open its privacy/site-data settings.
- Remove stored data for Microsoft sign-in, Outlook, Live, and Hotmail sites.
- Temporarily disable ad-blocking or privacy extensions and allow cookies, including third-party cookies.
- Close all browser windows.
- Reopen the browser and use the official Outlook sign-in link: outlook.live.com. Do not use an old Hotmail bookmark.
A stuck sign-in session or blocked authentication cookies can produce a login loop; clearing the relevant cookies and entering through the current Outlook address resets that session.^3^
3. Determine whether this is mailbox-specific
Try opening Outlook through the mobile Outlook app or another device/network, such as a phone using cellular data.
- It works there: The account and mailbox remain accessible; concentrate on site data, extensions, or the original network.
- It fails everywhere while other Microsoft account pages work: This points to an Outlook.com-specific access problem rather than necessarily an incorrect password. Use the next escalation path rather than repeatedly attempting to sign in.
4. Use the sign-in recovery route
Run Microsoft’s sign-in troubleshooter. Hotmail now signs in through Outlook.com using the same username and password as the Microsoft account.^1^
If Outlook.com remains inaccessible, Microsoft directs users who cannot sign in to the Microsoft account sign-in helper; Outlook.com support cannot directly assist with sign-in problems for account-protection reasons.^4^
Avoid repeated password resets unless the troubleshooter identifies a credential problem—the spinning logo and blank page do not by themselves establish that the password is wrong.
