Temporarily Remove Your Hotmail Account From Your iPhone

1. Open the Settings app.
2. Select Passwords & Accounts.
3. Select Hotmail under Accounts.
4. Tap Delete Account.
5. Go back to Passwords & Accounts.
6. Tap Add Account.
7. Select Other below the list of potential email providers.
8. Enter your Hotmail Login information.

Why this works:

Sometimes, your email account’s integration into your iPhone’s software can become corrupted. Similarly to deleting a malfunctioning app, briefly removing your Hotmail account from your iPhone might give your device a chance to form a smoother connection with the account.

This step only applies to people who use the Mail app on their iPhone. If you’ve never accessed your Hotmail account through the Mail app before, you can skip this step and move on to the next one.
