Delta Import vs. Full Import
Delta Imports are more efficient than Full Imports because only changes are updated. The MA
needs to be able to support Delta Imports because a tracking mechanism (or field) is required.
For example, Active Directory uses the Update Sequence Number (USN) as a tracking
mechanism. If an MA does not support Delta Imports, it does not mean that you cannot synchronize
the information. You will just have to find an alternate solution; for example, you might have to
rely on Full Imports.
After data is imported, it can be synchronized. Synchronization affects objects and
attributes. Delta synchronization will affect only objects and attributes that have changed since
the last synchronization. Full synchronization affects all objects and attributes. The import
and synchronization steps are usually combined as a single process.
Initiating an unscheduled directory synchronization using
Synchronization Service Manager
Using the Synchronization Service Manager to initiate directory synchronization is a
twophase effort, or four phases if we need to write information back to AD because of a hybrid
Exchange setup:
Synchronize (read) changes from AD
Synchronize (write) changes to Office 365
Synchronize (read) changes from Office 365 for fields associated with hybrid
Exchange setups (only for hybrid scenarios)
Synchronize (write) changes to AD for fields associated with hybrid Exchange setups
(only for hybrid scenarios)
