Get Message List


  • In order to successfully use this endpoint to request message lists for any user, the logged in user must be a Mimecast administrator with at least the Archive | Search | Read permission.
  • To use this endpoint to request message lists for the logged in user or an address that the logged in user has delegate permission to, no administrator permissions are required.


To use this endpoint you send a POST request to:

  • /api/archive/get-message-list

Request Headers

The following request headers must be included in your request:

Field Description
