Symptoms
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.
