PowerShell scripts for calendar folder permissions

Calendar Folder Permissions

Calendar folder permissions include permissions such as publishing and sharing of calendar events. There are no built-in reports in EAC (Exchange Admin Center) to view information about these calendar folder permissions. You have to rely on PowerShell scripts to get the details. Below are some Powershell scripts that will help you to view the permissions for a specified calendar folder, and delegate calendar access rights to users.

There's an easier way than executing the PowerShell scripts. Check out built-in calendar folder permissions reports offered by Exchange Reporter Plus to get all the insights you need on calendar folder permissions instantly.
