Exchange 2016 – There is no existing permission entry found for user.

There is no existing permission entry found for user: running Set-MailboxFolderPermissions


You receive the following error when trying to run the Set-MailboxFolderPermissions in Exchange 2016 EMS.


There is no existing permission entry found for user: Su-Yu-Chan Rack  –  Nerd.

+ CategoryInfo          : NotSpecified: (:) [Set-MailboxFolderPermission], UserNotFoundInPermissionEntryException

Since Exchange 2013 there has been a changed in PowerShell cmdlest when it comes to Set-MailboxfolderPermissions.

Use the Set-MailboxFolderPermission cmdlet to modify folder-level permissions for users in mailboxes. The cmdlet differs from the Add-MailboxFolderPermission cmdlet in that it modifies existing permission entries.

So that means we need to use the Add-MailboxPermission cmdlet to add permissions to a mailbox.



This example grants the user Mark Steele Full Access permission to Jeroen Cool’s mailbox and disables the auto-mapping feature.

To resolve the error which I have received I simply had to change to “Set” to “Add”



Sharing is caring!
