MS Outlook error message – You do not have permissions
Hello There! We are using MS Exchange 2013 and MS Outlook 2010 and 2013. In 2010, We have no issues. We have dedicated three room admin and they get all the requests for my rooms booking. But in MS Outlook 2013, We got an error messages when anyone tries to book room saying "you do not have permissions" Please advise on how can we fix this.
