Consider the following scenario in Microsoft Exchange Server 2019 or Exchange Server 2016:

  • You enable the Active Directory split permission model by using this command:

setup.exe /PrepareAD /ActiveDirectorySplitPermissions:true

  • You use the following command to check whether the Mail Recipient Creation role is no longer assigned:

Get-ManagementRoleAssignment -Role "Mail Recipient Creation" -Delegating:$false | ft name

  • You run the following command, and you learn that the Set-MailboxFolderPermission cmdlet is part of the Mail Recipient Creation role:

Get-ManagementRole -Cmdlet Set-MailboxFolderPermission | ft

It's expected that the Set-MailboxFolderPermission cmdlet should be in the Mail Recipients role instead of in the Mail Recipient Creation role.


To fix this issue, install one of the following updates:

For Exchange Server 2019, install the Cumulative Update 8 for Exchange Server 2019 or a later cumulative update for Exchange Server 2019.

For Exchange Server 2016, install the Cumulative Update 19 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.
