Supported Exchange ActiveSync policy settings

June 25, 2014

Similar to Group Policy settings for PC operating systems, Exchange ActiveSync (EAS) mailbox policies allow an administrator to apply a common set of policy and security settings to a group of users. Windows Phone 8.1 supports the use of the Exchange ActiveSync protocol for synchronizing email, calendar, task, and contact information with Exchange Server or Microsoft Office 365.

Description

AllowSimpleDevicePassword

  • Specifies whether a simple device password is allowed. A simple password is a password that has only repeated "2222" or sequential “abcd" characters. The default is $true.

AlphanumericDevicePasswordRequired

  • Specifies whether the password for the phone must be alphanumeric. The default is $false.

DevicePasswordEnabled

  • Specifies whether a password is required. When set to $true, DevicePasswordEnabled requires that the user set a password for the phone. The default is $false.All service packs

DevicePasswordExpiration

  • Specifies the length of time, in days, that a password can be used. After this length of time, a new password must be created. The format of the setting is dd.hh.mm:ss; for example, 24.00:00 = 24 hours.

DevicePasswordHistory

  • Specifies the number of previously used passwords to store. When a user creates a new password, the user can't reuse a stored password that was previously used.

IrmEnabled

  • Specifies whether IRM is enabled for the mailbox policy.

IrmEnabled

  • Specifies whether IRM is enabled for the mailbox policy.

MaxDevicePasswordFailedAttempts

  • Specifies the number of attempts a user can make to enter the correct password for the phone before a device reset to factory settings is initiated. You can specify any number from 4 through 16. The default is 8.

MaxInactivityTimeDeviceLock

  • Specifies the length of time that the phone can be inactive before the password is required to reactivate it. You can specify any interval between 30 seconds and 1 hour. The default is 15 minutes. The format of the setting is hh.mm:ss; for example, 15:00 = 15 minutes.

    • Lowercase alphabetical characters

    • Uppercase alphabetical characters

    • Numbers

    • Non-alphanumeric characters

For example, if the value of MinDevicePasswordComplexCharacters is 2, a password with both uppercase and lowercase alphabetical characters would be sufficient, as would a password with lowercase alphabetical characters and numbers.

MinDevicePasswordLength

  • Specifies the minimum number of characters in the device password. You can specify any number from 1 through 16. The maximum length a password can be is 16 characters. The default is 4.
