Using the Windows Azure Graph API and the Azure Active Directory that underpins every Office 365 tenant, Office 365, users, user attributes and groups are replicated to the Mimecast platform.
Once the service is activated the Mimecast platform uses the Office 365 / Azure tenant name, and a predefined Azure Active Directory application to query the Windows Azure Graph API.
- 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.
Mimecast will sync with the Azure Active Directory automatically 3 times a day, starting at 8am, 1pm, and 11pm.
At this stage Mimecast does not support replicating the members of Office 365 Dynamic Distribution groups due to limitations in the Windows Azure graph API.
Learn how to set up this feature using the Enable Azure Active Directory Synchronization for Office 365 guide.
