I used this to get folder owner permissions on all public folders for the user daniel.
In Exchange Management Console:
Get-PublicFolder -recurse | Add-PublicFolderClientPermission -User daniel -AccessRights FolderOwner
Get-PublicFolder -recurse | Add-PublicFolderAdministrativePermission -User daniel -AccessRights AllExtendedRights
Hey Daniel,
This helped a bit, yet I am unable to edit permissions on some folders. I have for instance a folder called Corporate ICT with inside a task list. I cannot mark tasks created by others as completed or even see the permissions on the folder itself.
Any idea what is causing this?
