Booking resource calendars in Office 365

My customers asked about resource calendars and where do I increase the advanced booking settings in Office 365. This is done via powershell. You have to set-calendarprocessing “resource” –bookingWindowInDays 365.


In my case I only had one change to make so I could do the following:


Get mailbox –identity room1 | set-calendarprocessing –bookingWindowsInDays 365


You could change all resources by using the following:


get-mailbox | Where {$_.RecipientTypeDetails –eq “RoomMailbox”} | set-CalendarProcessing –BookingWindowInDays 365.


BTW – default setting is 180 days.
