Open an InPrivate or Incognito browser window, sign in at https://outlook.live.com with the complete @msn.com address, and use Microsoft’s Sign-in Helper if that browser sign-in fails.
Since restarting the computer did not help and mail is unavailable on both the computer and phone, troubleshoot the account or mailbox before changing the mobile app.
1. Test the account in a browser
- In Microsoft Edge, press Ctrl+Shift+N to open an InPrivate window. In Chrome, use Ctrl+Shift+N for Incognito.
- Go to https://outlook.live.com.
- Enter the complete MSN address, including @msn.com, and its Microsoft account password. MSN email uses the Outlook.com sign-in process.^1^
- Note the exact result:
- Mailbox opens: proceed to the mailbox and phone checks below.
- Incorrect password, account not found, locked account, or verification failure: use the Microsoft account Sign-in Helper at https://aka.ms/sign-in-helper. It checks the account details and provides the appropriate recovery action.^2^
- Page or mailbox will not load: check Outlook.com service status at https://admin.microsoft.com/servicestatus. If an incident is listed, wait for Microsoft to restore the service before removing accounts or changing passwords.^3^
If the password is accepted but has stopped working elsewhere, verify that the address spelling and domain are correct. If another email alias or phone number belongs to the same Microsoft account, it can also be used for recovery.^4^
2. If webmail opens but messages are missing
Check these items inside Outlook.com:
- Storage: open https://go.microsoft.com/fwlink/?linkid=2218097. If Microsoft cloud storage is full, the account cannot send or receive mail; messages sent while it was full are bounced back and cannot be recovered.
- Check both the Focused/Other tabs and the Junk Email folder.
- Select Filter → Sort → Date to ensure recent messages appear first.
- Review whether forwarding or inbox rules are redirecting messages.
Microsoft lists storage, filtering, Junk, forwarding, rules, and temporary account blocks among the common causes of missing Outlook.com mail.^5^
3. Restore mail on the phone only after webmail works
If messages appear correctly at Outlook.com but not on the phone, the remaining problem is with the phone’s mail connection:
- Microsoft Outlook app: remove the MSN account or its synchronization partnership from Outlook, then add the account again using the complete @msn.com address. Microsoft documents removing and re-adding the sync partnership when an Outlook.com account previously synchronized but has stopped.^3^
- Apple Mail, Gmail, Samsung Email, or another app: remove and re-add the account through that app’s account settings. If Outlook.com works in the browser but the third-party app still fails, contact that app’s support; Microsoft recommends Outlook Mobile for Outlook.com accounts.^3^
Do not remove the phone account until browser access is restored and the password is known.
If recovery still fails
Outlook.com support cannot manually bypass account sign-in protection. Use the Sign-in Helper for inaccessible accounts.^6^
If browser access is restored but the mailbox still does not work, select Help in Outlook.com, enter the problem, then scroll to Still need help? and select Yes to contact Outlook.com support.
