In Easy365Manager, you can enter a number in the “Booking window (days)” to define the number of days in advance that users can schedule meetings in the designated room.
Watch a quick video guide here.
You can quickly locate the setting by opening up properties for a Room user, selecting the Mailbox tab, and clicking on Room Settings.
This opens up the following form, where you will find “Booking window (days)” in the Booking Processing section:

In Easy365Manager, the setting “Booking window (days)” corresponds to the ‘BookingWindowInDays’ parameter of the Set-CalendarProcessing PowerShell command.
The “Set-CalendarProcessing -BookingWindowInDays” PowerShell command allows administrators to control the time frame in which users can book or request meetings in a specific meeting room’s calendar.
Set-CalendarProcessing -Identity "Shanghai-MeetingRoom301" -BookingWindowInDays 30
By adjusting the booking window using this command, organizations can enhance scheduling efficiency. For instance, setting a longer booking window can provide flexibility for users to plan meetings well in advance, preventing last-minute scheduling conflicts. On the other hand, a shorter booking window might help optimize room utilization by discouraging excessive advance reservations, ensuring that rooms remain available for spontaneous or urgent meetings.
