Exchange Online Synchronisation

Hello,

I've installed  Exchange Online connector and started a sync project in sync editor.

I've already installed an Azure Ad connector, setup a synch project in the past.

In one identity manager, i cannot find how to link an exchange online account to a business role for example?

For  Azure Ad connector, i've created a AZure_AD_Ressource and pointing to AADUSer table, and attached this a business role, so every one having this role will have an azure ad account.

How to do the same for Exchange online , can i create a ressource (what table to point to?) and automate onboarding persons into Exchange online via a business role?

Many thanks
