Manage how users use email and im on their phones

As the admin, you can set up mobile phone and tablet access options for Microsoft 365 on the Admin home page: Service settings > Mobile access. These settings apply to all the phones and tablets in your organization, including your own.

Most phones and tablets work with Microsoft 365, including those that run Android, Apple iOS (iPhones and iPads), Symbian (Nokia), and Windows Phone. For more information about setting up email and other services on a mobile device, see Set up and use Office 365 on your phone or tablet.

Turn off Microsoft 365 email on phones and tablets

People can set up their mobile phones and tablets to use Microsoft 365 email unless you turn off the option. It's a global setting, so if you turn it off, no one in your company can access their Microsoft 365 email from a mobile device, including you.

1. Go to Admin > Service settings > Mobile access.

2. Turn off Email.

Require a password on phones and tablets for better security

You can require that people type a password to access their phones and tablets. This helps make your organization's information more secure because it prevents someone else from reading company email messages if they pick up a phone or tablet that isn't theirs.

1. Go to Admin > Service settings > Mobile access.

2. Click Device security settings.

3. Select Yes to require passwords.

After you set this password requirement, phones and tablets that already have Microsoft 365 email, and phones and tablets that people set up later, will prompt people to set a password.

If you want to require longer passwords or set other password options, you first have to make passwords required.
