You can use the mailbox delegation feature to grant access to an employee to handle the Exchange folders of another employee on their behalf. For example, an executive assistant can manage their executive's mailbox based on the permissions set by the executive.

When enabling the mailbox delegation, you must determine a delegate and a delegator. A delegator is the actual owner of the mailbox, and a delegate is a user added to manage the mailbox. For example, an executive is a delegator, and the executive assistant is the delegate.

Note: Workspace ONE Boxer supports only a full calendar delegation. It does not support the sharing of individual subfolders. For example, you cannot share individual subfolders such as a calendar or a mailbox folder using your Outlook desktop application. To configure delegation, you must use the Exchange admin center.

As a delegator, you can set the following permission levels for your delegates to access your mailbox:

  • Full Access - Delegates can read and triage your emails.
  • Send As - Delegates can send emails on your behalf. For example, a delegate can draft and send an email directly from your mailbox.


  • Delegate can only add five delegators to Boxer.
  • You cannot delegate Contacts, Tasks, and Notes in Workspace ONE Boxer.
Note: If you are using Exchange Server 2013 or later with the Calendar Delegation enabled in the Exchange admin center, no additional configuration is required for the Mailbox Delegation.
