Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Micah,
Thanks for the detailed information.
Based on the PowerShell result, I found BookingWindowInDays and MaximumDurationInMinutes for the problematic are both set to 0.
If BookingWindowInDays is set to 0, the room cannot be booked in advance. This setting specifies the maximum number of days in advance that the room can be reserved.
MaximumDurationInMinutes specifies the maximum duration allowed for a meeting in this room. If it’s set to 0, the maximum duration is unlimited.
The AllRequestOutOfPolicy specifies whether to allow all users to submit out-of-policy requests. Out-of-policy requests are subject to approval by a resource mailbox delegate.
In this situation, I suggest you change the BookingWindowInDays to another value. The default value is 180 days as the Big room.
You can run the command to change the value: *Set-CalendarProcessing *****@contoso.com -BookingWindowInDays 180(Or any other value based on your requirement).
This setting can be also found in EAC.
Let me know if the issue persists.
Thanks,
Chris
