You can use the the Azure Graph API and the Azure Active Directory in every Office 365 tenant, to replicate users, user attributes, and groups to the Mimecast platform. Once the service is activated, synchronization between Mimecast and Azure Active Directory occurs automatically three times a day starting at 8am, 1pm, and 11pm.
The Mimecast platform uses the Office 365 / Azure tenant name and a predefined Azure Active Directory application, to query the Windows Azure Graph API. The workflow is:
- User, user attribute, group, and group membership data is requested from the Windows Azure Active Directory.
- Windows Azure Active Directory returns the requested data, which is in turn processed and committed to the Mimecast platform.
We do not support replicating members of Office 365 Dynamic Distribution groups, due to limitations in the Windows Azure graph API.
