Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
The repeated sign-in loop usually happens because of browser security/cookie settings or using different account types during authentication.
Try these steps in order:
- Update browser security/cookie settings (especially Edge/Internet Explorer)
- Make sure these sites are not in the Trusted sites list, or that all of them are there together so cookies can be shared correctly:
-
microsoft.com -
support.microsoft.com(and any subdomains) -
login.live.com -
login.microsoftonline.com
-
- After adjusting the Trusted sites list, close all browser windows and sign in again. This fixes most “redirect back to the same sign-in page” loops.
- Make sure these sites are not in the Trusted sites list, or that all of them are there together so cookies can be shared correctly:
- If using a personal Microsoft account
- Go to https://login.live.com/ and sign in successfully there first.
- In a new tab, go to support.microsoft.com and try to access support again.
- If using a work/school (Microsoft Entra ID) account and blocked by MFA after many attempts
- Microsoft Entra multifactor authentication may temporarily block sign-in after repeated attempts.
- Wait and try again later, or use a different MFA method if one is configured.
- If the issue persists, contact the organization’s IT administrator and ask them to review Microsoft Entra sign-in logs and MFA configuration.
- If still unable to reach support
- Use any working Microsoft account (personal or work/school) to sign in and then use the Contact Support/Get Help flow on the Microsoft Support site to reach a support agent.
If the account itself cannot be accessed (for example, locked or password cannot be changed), follow the appropriate “get help with your Microsoft account” or work/school account password help from the referenced articles below.
