Issues with Room Reservations

Question

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.

Answer 2

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 Room@contoso.com | select ScheduleOnlyDuringWorkHours

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