Sending, receiving, and organizing email in Outlook.com
If Outlook works in the Outlook app but not through Safari, focus on the Safari sign-in path first.
- Check Safari version. Outlook.com access in Safari requires Safari 16 or newer.
- If the problem is in Apple Mail or the iPhone/iPad account screen tied to Safari sign-in, remove and add the account again as Outlook.com.
- Go to Settings > Mail > Accounts.
- Select the affected account and remove it.
- Go back to Settings > Mail > Accounts > Add Account.
- Choose Outlook.com and sign in again.
- If removing and re-adding does not fix it, clear Safari website data, then try again.
- Go to Settings > Safari.
- Tap Clear History and Website Data.
- Reboot the iPhone.
- Add the account back and complete the Outlook.com sign-in flow again.
- If Safari shows a Microsoft sign-in error such as:
- “Something went wrong and we can't sign you in right now.”
- “Solve a puzzle so we know you're not a robot.” then use the Microsoft account recovery article for Error 400 when signing in.
- If Safari says the password is wrong, recover the Microsoft account first, then sign in again.
- If a verification code prompt appears and the code fails, use the Microsoft verification code troubleshooting article before retrying sign-in.
If the Outlook app continues to work, that usually means the account itself is still valid and the issue is isolated to the Safari-based authentication flow or the Apple Mail account connection.
