Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Sandeep,
Yes. If you want to sync the users between On Premise and Office 365 cloud, you can use Office 365 SMTP match during AAD Connect. For more information, you can refer to https://support.microsoft.com/en-ca/help/2641663/how-to-use-smtp-matching-to-match-on-premises-user-accounts-to-office.
Also, you can use Exchange Server to set up Hybrid mode later.
Regards,
Barry
