The Enable-RemoteMailbox is a command available in the on-premises Exchange Server PowerShell module.
Enable-RemoteMailbox is used to provision an Office 365 mailbox for an existing on-premises user object.
It is not a hard requirement that the user is already synchronized to Azure AD, but you’ll find that the mailbox creation is much faster and less error-prone if you run this script after synchronizing the user object.
Running the Enable-RemoteMailbox CmdLet looks similar to this:
[PS] C:\>Enable-RemoteMailbox amy.cooper -PrimarySmtpAddress "email@example.com" -RemoteRoutingAddress "firstname.lastname@example.org" Name RecipientTypeDetails RemoteRecipientType ---- -------------------- ------------------- Amy Cooper RemoteUserMailbox ProvisionMailbox
Notice that the Office 365 account is not licensed automatically.
For a shared mailbox, that’s fine, but for standard users, you need to assign an Exchange Online license before the 30-day grace period expires. This can be done via the Microsoft 365 Admin Center (or directly from AD user properties if you’re running Easy365Manager).
You’ll also need AD Users & Computers to configure additional properties of the on-premises users.
If you wish to configure mailbox settings like delegation or calendar sharing you’ll need to visit either the Exchange Online Admin Center or Exchange Online PowerShell.
Finally, you’ll need to create a remote PowerShell connection to Azure AD Connect to force a replication (unless you want to wait up to 30 minutes before all pieces are glued together).
