Cmdlets to create or modify a remote shared mailbox in an on-premises Exchange environment

Starting in Cumulative Update 21 for Exchange Server 2013 and Cumulative Update 10 for Exchange Server 2016 in an on-premises Exchange Server environment, you can directly create or modify a remote shared mailbox by using the new parameter -shared with the following cmdlets:

• Enable-RemoteMailbox: [-Identity user] [-Shared] [-RemoteRoutingAddress user@domain]
• New-RemoteMailbox: [-Shared] [-Name remoteMailboxName]
• Set-RemoteMailbox: [-Name user] [-Type Shared] 

Exchange Server 2016

To enable the parameter -shared so that it will work, make sure that you prepare Active Directory by running the following command:

<path_to_Exchange2016CU10_or_LaterBuild>\setup.exe /PrepareAD /OrganizationName:”first_organization_name” /IAcceptExchangeServerLicenseTerms

And install the same build of Cumulative Update 10 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.

Exchange Server 2013

To enable the new parameter -shared so that it will work, make sure that you prepare Active Directory by running the following command:

<path_to_Exchange2013CU21_or_LaterBuild>\setup.exe /PrepareAD /OrganizationName:”first_organization_name” /IAcceptExchangeServerLicenseTerms

And install the same build of Cumulative Update 21 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013.
