When setting up room resources and room lists in Exchange / Office 365 the default work hour is set to between 8:00 AM to 5:00 PM in the time zone of the room resource. This results in rooms not showing up in room lists outside of these hours. Luckily, there is a way to solve it. This article will show you how to customize the work hours and room lists on Exchange / Office 365.
- Connect to Exchange PowerShell either locally on the server or online.
- To modify the work hours of a specific room resource in your organization use the following PowerShell command:
Set-MailboxCalendarConfiguration -Identity <PrimartySMTPofRoomResource> -WorkingHoursStartTime 00:00:00 -WorkingHoursEndTime 23:59:59
or if you want to modify all rooms resources:Get-MailBox | where {$_.ResourceType -eq "Room"} | Set-MailboxCalendarConfiguration -WorkingHoursStartTime 00:00:00 -WorkingHoursEndTime 23:59:59
Note: Replace 00:00:00 23:59:59 with the start time and the end time if you do not want to have the access day on.
