help I can't get my hotmail on iphone now

I've seen this with google as well, had to go through and set up a specific password for the ipad through the gmail settings to get it so I could log it in. You may have to do that or, disable the Two Step Verification

Get an App Password for Outlook

Once you’ve set up two-step verification, you need to obtain an App Password to be able to connect again via the Outlook Hotmail Connector or the EAS protocol.

1. In your account management go back to Security Info.
2. Under the “App passwords” header, click on: Create a new app password
   You can also use this direct link to the App Password section.
3. Use the generated password which is being displayed to log on to your Outlook.com account from Outlook.

Getting an App Password for Outlook is required after enabling Two-Step Verification for your Microsoft Account.

Note: Although you can reuse this password for other apps, it is not recommended or needed to save this password for future reference. Just create a new one when you are being prompted for a password in another application which doesn’t support two-step verification. If any of the passwords become compromised, use the “Remove existing app passwords” link in the “Security info” section to make them invalid.
