Azure AD synchronisation : delete users in target system

Hello,

In my Azure AD project synchronisation, when the users is deactivated in One identity manager, the Azure Ad user account in One Identity manager  is 
strikethrough and  the user in AzureAd and Office 365 is only marked as 'Connection blocked'.

I want when the process off deactivation (deletion) is trigerred in One identity manager:

-Azure Ad user account in One Identity manager  deleted

- Synchronized user in AzureAd and Office 365 also deleted

Thank you for helping
