We are experiencing issues with room reservations (Outlook). During certain bookings, some users are being denied access to rooms at specific times, such as a denial at 1 a.m.

Additionally, another user reserved a room that was available at the time of booking, but several hours later, they received a reservation rejection. This issue is not limited to a single room but affects multiple rooms, and we have several similar cases.

Could you please help us resolve this problem? It is impacting a majority of employees who use the rooms for their interviews with candidates.

    Hi,@Hinnata saku

    Thanks for posting your question in the Microsoft Q&A forum.

    According to your description, you have a problem with room bookings in Outlook. I need to confirm a couple of issues with you:

    1.Are you using an Exchange mailbox? If so, are you using On-prem Exchange or Exchange Online?

    2.Are you the mailbox administrator?

    3.Are you having the same problem after recreating the rooms mailbox?

    Here are my suggestions:

    1.Run the following PowerShell cmdlet to view the booking policy:

    Get-CalendarProcessing -Identity <resource mailbox> | FL
    

    2.You can investigate resource booking issues using the Booking Attendant log at this link:https://learn.microsoft.com/en-us/exchange/troubleshoot/calendars/use-resource-booking-attendant-logs

    To better solve your problem, I hope you can provide some screenshots of the reported errors.

    Regarding your first issue, the specific room mailbox might have configured with work hours restriction. If you try to book room in non-working hours, you will be denied.

    To check the work hours restriction, use the below cmdlet.

    Get-CalendarProcessing -Identity ******@contoso.com | select ScheduleOnlyDuringWorkHours

    If it returns true, you need to set it as False to allow booking all the time.
