Start profile synchronization manually in SharePoint Server
Summary: Learn how to start profile synchronization manually in SharePoint Server 2013 or SharePoint Server 2016.
This article describes how to start profile synchronization for SharePoint Server manually. You can start a full synchronization or an incremental synchronization of profile information. You might want to consider starting profile synchronization manually if you have made considerable changes to user profiles, and you don't want to wait for the next scheduled synchronization.
Note that this procedure is only for SharePoint Server farms that are using SharePoint Active Directory Import. If you are using an external identity manager, see the documentation for your identity manager.
Start profile synchronization manually
You can manually start a full synchronization or an incremental synchronization of profile information. You need to be a farm administrator or an administrator of the User Profile service application to perform this procedure.
Usually, an incremental synchronization is fine, but you should use a full synchronization if any of the following are true.
A mapped property has changed. For example, you mapped a new property, or added or changed a mapping associated with a property.
You changed the containers that a connection uses to synchronize with AD DS.
You added or deleted a synchronization connection.
Keep in mind that a full synchronization can take a long time, depending on the size of your directory.
