In Easy365Manager, the “Selected delegates can book” setting corresponds to the ‘BookInPolicy’ parameter of the Set-CalendarProcessing PowerShell command.
The “Set-CalendarProcessing -BookInPolicy” PowerShell command allows administrators to define who can schedule meetings in a designated meeting room:
Set-CalendarProcessing -Identity "Riverside16-ConfRoom-5.6" -BookInPolicy "Amanda Gray", "Amanda Smith"
By using this command, administrators can easily restrict the booking permissions for a meeting room to a specific set of users or groups, ensuring that only authorized personnel can schedule meetings in that room. This enhances the efficiency of resource allocation and prevents unauthorized bookings, reducing scheduling conflicts and ensuring a smoother meeting room booking process.
The “Set-CalendarProcessing -BookInPolicy” PowerShell command empowers administrators to finely control meeting room scheduling by defining a list of individuals or groups allowed to book the room. This improves resource management, reduces scheduling clashes, and streamlines the overall booking process within an Exchange environment.
