In Exchange, you may notice that when you try and book a meeting room, you cannot go higher than 180 days. This is by default.
To change this, you can run a simple PowerShell command and increase the value, take note you cannot go higher than 1080 days.
The command to change this is as follows:
- Set-CalendarProcessing -Identity “Boardroom” -BookingWindowInDays 365
Give it time to replicate and then you should be able to increase the Booking Window.
Hope it helps.
