Exchange Tasks are the mechanism that applies settings configured in definitions to a Mimecast Synchronization Engine instance and ultimately to Exchange mailboxes. An Exchange task consists of the following:


The Mimecast Synchronization Engine siteWhich instance of Mimecast Synchronization Engine the task should be executed by.
Type and Definition

The type of feature being configured:

  • Mailbox Folder Replication
  • Calendar Replication
  • Mailbox Storage Management
  • Managed Folders

Each type also has specific settings defined for that feature.

ScheduleWhen and how frequently the task should be executed.
A group

Which mailboxes should the task execute the configured definition for. An Exchange task can be applied to:

  • an Active Directory Security group
  • an Active Directory Distribution group
  • an Office 365 distribution group (requires v2.7 or later)
  • a single mailbox (requires v2.7 or later)
  • a list of mailboxes (requires v2.7 or later)


Creating Exchange Tasks


To create an exchange task:

  1. Log in to the Administration Console.
  2. Click on the Administration toolbar button. A menu drop down is displayed.
  3. Click on the Services | Exchange Services page.
  4. Select the New Exchange Task button in the menu bar to get started.

  5. Select the Synchronization Engine Site where the task should run.
  6. Select an existing Schedule from the drop down list or use the Create New button to make a new one.
  7. Select your Task Type.
  8. Select an existing definition for the specific Task Type selected or use the Create New button to make a new one.
  9. Select a Group to apply the task to. There are a number of options for selection:

    Lookup from ADUse this option when you have synchronized your Active Directory with Mimecast and you have a specific Active Directory Security or Distribution group that you would like to apply the task to.
    Enter DN manually

    Typically this option is available for customers who have not synchronized their Active Directory with Mimecast. If your organization is  in this situation you can manually enter the full DN for a specific group, for example:


    Enter group email address

    This option is aimed at Office 365 customers. Enter the email address of an Office 365 Distribution Group and the Synchronization Engine will use Office 365 to resolve the members of that group.


    This option can also be used to enter the email address of a mailbox or group of mailbox addresses using a ';' separated list. This can be useful when you want to target an Exchange Task in a small group of mailboxes.

  10. Select Save and Exit. Your Exchange Task has now been created and will be applied to the Synchronization Engine Site selected.
