getting this error every time i try to change the information for a users mailbox.
Error executing request. The operation on mailbox "User" failed because it's out of the current user's write scope. The action 'Set-Mailbox', 'Alias,DisplayName', can't be performed on the object 'User' because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization.
thank you
