Background

We have various scenarios where it’s necessary to locate the manager of a particular user. For instance, to identify the manager as an Approver, or to send reminders/notifications to the manager.

Although there is a manager field within the user table, this field is always Null, therefore, we are eager to know how to synchronize the Manager field from O365 into the D365 user table.

There is no "Manager" property in the AAD User table either.

Below content is a summary of the reply from the Microsoft CSS Team.

1, There’s no hierarchy concept in the Dynamics CRM Application.

2, The manager property is not synchronized when the user is synchronized from O365/AAD to Dynamics 365 CRM.

3, There is no way to configure the attribute mapping and no public document about it.

4, Below table is the mapping table for your reference.
