Hi, I need some help enabling an AD user to be able to write/edit a shared calendar using Exchange Management Shell. Although I was added as an owner for the shared calendar using outlook, I am still not enabled to change permissions using outlook (although this is a separate issue, does anyone know why that would happen?), so I am looking for a workaround using the management shell. Can someone please provide the exact powershell command? I am new to powershell. Thank you! Jason jason

Do the users have the "Receive As" permission on those calendar accounts?Are the calendar permissions assigned at the folder level, or as a delegate in Outlook?http://msexchangeteam.com/archive/2006/01/25/418099.aspx

Hi,To grant the permission on the certain folder which belongs to the folder permission. I didn't find any command could do this operation in EMS.You can use PFDAVAdmin tool to check the permission.http://www.msexchange.org/articles/PFDavAdmin-tool-Part1.htmlThanksAllen
