Outlook.com not working therefore iPhone not working

Question

Outlook.com not working therefore iPhone not working!

Answer 1

Hi, I'm John!

To help narrow down the issue:

1. Are you unable to sign in at https://outlook.live.com on a browser?
2. Or does the website open but emails are not loading or sending?
3. Also, on your iPhone: Are you using the Outlook app or the iPhone Mail app? What error message are you seeing on the phone?

If Outlook.com itself is not working in a browser, the issue is likely with the account or service.

If it works in the browser but not on the iPhone, it may just be a sync or app issue.

Please share what you see and any error message. That will help narrow down the cause.

If Outlook.com is not working and email is also not working on an iPhone, the issue is usually either a service problem on Outlook.com or a sync/authentication problem between the mailbox and the iPhone.

Use these checks and fixes:

1. Check Outlook.com account status

• If the mailbox or cloud storage is full, sending and receiving email will stop and messages sent to the account while full are bounced and unrecoverable. Check mailbox storage and free up space if needed.
• If sign-in to Outlook.com fails or the account is blocked due to unusual activity, use the Microsoft account sign-in helper and, if needed, follow the steps to unblock the Outlook.com account.

2. Fix mobile sync issues by removing the device partnership If email works in Outlook.com on the web but not on the iPhone, reset the sync partnership:
3. Sign in to Outlook.com in a browser.
4. Go to Settings > General > Mobile devices.
5. Select the iPhone in the list and delete the device partnership.
6. Select Save.
7. Power off the iPhone completely, wait a few seconds, then turn it back on and let it sync again.
8. If using Apple Mail on iPhone If the Outlook.com account is added in the iOS Mail app and there are password prompts or connection errors:
9. On the iPhone, go to Settings > Mail > Accounts.
10. Delete the Outlook.com account.
11. Go back to Settings > Mail > Accounts > Add Account.
12. Choose Outlook.com (not “Other”) so that modern authentication (OAuth) is used.
13. Complete the Outlook.com sign-in flow.

If removing and re-adding does not work:

1. Remove the account again.
2. Go to Settings > Safari and tap Clear History and Website Data.
3. Reboot the iPhone.
4. Add the Outlook.com account again as Outlook.com and sign in.
5. If using the Outlook mobile app on iPhone

• If Outlook for iOS was syncing before and stopped, follow the Outlook.com sync guidance above and consider deleting the phone partnership, then re-adding the account in the app.
• If the Outlook app itself is not functioning (crashing or unresponsive), clear the browser cache on the device, then remove and reinstall the Outlook app from the iOS App Store.

If email works on a computer and there is no Outlook.com outage, but the iPhone still cannot sync after these steps, the issue is likely with the iOS email app itself, and contacting Apple Support or using the Outlook mobile app is recommended.
