  • Customers who are using Mimecast for email security.




Azure SynchronizationBefore users can send and receive email or sign in to our applications, they need a user account. By synchronizing your directory with us, we automatically create each user's Mimecast account.


This has a number of benefits, including:

  • Enabling features based on Active Directory groups to reduce administrative overhead.
  • Configuring policies based on Active Directory groups or user properties.

While we recommend you synchronize your Active Directory with us, it is not mandatory. If you prefer, you can manually import user data by completing the Add Additional Users task in the Connect Application.

Synchronizing Your Directory


To synchronize your Active Directory with us:

  1. Log on to the Connect Application.
  2. Navigate to the Platform | Synchronize Your Directory menu item.
  3. Click the Start button in the section for the synchronization method you want to use. The available methods differ according to your Exchange type:

    Synchronization MethodOffice 365On PremiseHybridG Suite
    Azure Active DirectoryYesNoYesNo
    Mimecast Synchronization EngineNoYesNoNo
    G SuiteNoNoNoYes
  4. Follow the instructions listed in the relevant article.

* See the Prepare your LDAP Directory page in the G Suite Administrator Help 

If you have already created a Directory Connector using the Administration Console, an option is presented to use it rather than create a new one.
