Text Box


In Office 365, you can create mobile device mailbox policies to apply a common set of policies or security settings to a collection of users. These policies allow an organization to create secure settings for the action of accessing company’s data through a mobile device. A default mobile device mailbox policy is created in every Office 365 organization. 

Mobile device mailbox policies can be created in the Exchange admin center (EAC) or Exchange Online PowerShell. If you create a policy in the EAC, you can configure only a subset of the available settings. You can configure the rest of the settings using Exchange Online PowerShell. 

Settings Of Mobile Device Mailbox Policies 

You can use mobile device mailbox policies to manage many different settings. These include the following: 

  • Require a password 

  • Specify the minimum password length 

  • Allow a numeric PIN or require special characters in the password 

  • Designate how long a device can be inactive before requiring the user to re-enter a password 

  • Wipe a device after a specific number of failed password attempts
