    Hi @Ahmed Essam,  

    Microsoft 365 and Office 365 provide a mail migration advisor to help you move mailboxes from your current on-premises Exchange server to Exchange Online in Microsoft 365 and Office 365 with automated tools and step-by-step guidance. Use the Microsoft 365 and Office 365 mail migration advisor | Microsoft Learn  

    Since you have Exchange 2016 server, if your on-premises Exchange organization has fewer than 2,000 mailboxes. you could use the cutover migration method.

    Please note that if you have turned on directory synchronization, you need to turn it off before you can perform a cutover migration. You can do this by using PowerShell. For instructions, see Turn off directory synchronization.
