iPhone Keeps Asking for Outlook Password: Try These 5 Fixes


Does your iPhone keep asking for your Outlook password? Opening the Mail app only to be met with a constant barrage of pop-ups about your login credentials can be a major productivity killer. Sure, it only takes a minute to enter and confirm your username-password combination, but imagine doing that several times an hour. To help you regain full access to your account, here’s what you should do.

Why Does Your iPhone Keep Asking for Your Outlook Password?

iOS updates are loaded with features and improvements, but they also introduce problems. If your iPhone starts prompting for your Outlook password after an update, it’s probably because the system software is interfering with Mail.

Another reason is for security verification. If you add Outlook as an Exchange or Other account to Mail, it may end up using a less secure form of authentication. Microsoft doesn’t like that, so you’ll have to type in your Outlook password repeatedly as a protective measure.

The network configuration on your iPhone could also play a factor. For instance, communication issues between Mail and Outlook due to corrupt network settings might result in frequent requests for your email password.

You can stop prompts for your Outlook password following an iOS update by disabling and re-enabling the Outlook account on your iPhone. To do that:
