Email quit working

Check Microsoft’s service-health page before changing either device, because there is a current Outlook service issue that can prevent new Outlook.com mail from reaching multiple devices simultaneously.^1^

1. Determine whether this is the current outage

1. Open the Microsoft service-health page.
2. Look for an Outlook.com or Microsoft consumer-services incident.
3. If an incident is shown, wait until its status says it is resolved. Do not remove the account from both devices during the outage.
4. After resolution, close and reopen Outlook on the iPhone and Kindle Fire and check for new mail.

2. Test the mailbox in a web browser

Open Outlook.com in a browser and sign in by manually entering the complete email address, including @outlook.com, @hotmail.com, @live.com, or @msn.com.

• If new messages are also missing on the website: this is an account or service problem, not synchronization on both devices.
• If the website receives mail normally: the mailbox works, and the mobile Outlook apps need attention. Microsoft specifically says that when email works on a computer and no outage exists, the problem may be with the email app.^2^

3. If mail is missing on the website too

Check the mailbox’s Microsoft cloud storage. A full storage allocation prevents both sending and receiving; messages sent while it was full are rejected and cannot later be recovered.^3^

Also check on Outlook.com:

• Other and Junk Email
• Filter → Sort → Date
• Settings → Mail → Rules
• Settings → Mail → Forwarding

If “Address does not exist” appears while signing in, carefully re-enter the complete address. If the same address cannot sign in on the web, use Microsoft’s account sign-in recovery option from the Outlook.com troubleshooting page.^3^

4. If web mail works but the mobile apps do not

On each device, first update Outlook through its app store and reopen it.

For the Kindle Fire/Android Outlook app, Microsoft recommends checking Outlook.com server status first. If there is no outage, open Outlook, select the profile icon, then Help & Feedback → Contact Support to create an in-app support ticket.^4^

If the iPhone is actually using Apple’s built-in Mail app rather than Outlook, reauthenticate it:

1. Open Settings → Mail → Accounts.
2. Select the Outlook/Hotmail account.
3. Open Account Settings or the password field.
4. Enter the current password and tap Done.
5. Open Mail and verify that synchronization resumes.^5^

Only consider removing and adding the account again after the service incident is resolved, web mail works, and updating or reauthentication does not restore synchronization.
