Trying to give client full access to an exchange mailbox. User is already added to the mailbox i want to give full permission to.
when i click on manage i get this error.
"Some controls aren't valid"-Changes in the user/group list are required to grand or remove permissions.
I have done a thorough search on-line and still have no luck with this issue.
I have checked and enable inheritance for this object.
I have tried commands involving "add-mailboxpermission" in powershell get a error saying this is not a recognized as the name of a cmdlet.
Anyone have any tips for this it would be greatly appreciated.
