Question

When I try to Book a conference room it shows locations are unavailable and shows Redmark

Answer 1

Dear EA Chalama balagopala,

Thank you for posting your question on the Microsoft Q&A forum.

Based on the screenshot you provided, it appears that the room mailbox has automatically declined the booking. This typically happens due to scheduling conflicts or room booking policies configured in Microsoft 365. Please kindly check the following:

1/ Check if the Room is Already Booked

Open Scheduling Assistant (next to the time field) and review the room’s availability.

If the time slot shows as busy (solid block), the room is already reserved.

Please try selecting another available time slot.

For reference: Use the Scheduling Assistant and Room Finder for meetings in Outlook - Microsoft Support

2/ Check Room Booking Policies

Conference rooms are managed by automatic processing rules set by your IT administrator. The room may decline the meeting if:

• The meeting is scheduled outside allowed working hours
• The booking duration exceeds the maximum limit
• The booking is too far in advance
• Recurring meetings are restricted
• A minimum booking duration requirement is not met

If that, you can try:

• Schedule the meeting within business hours
• Reduce the meeting duration
• Book a single occurrence instead of a recurring meeting

If the room continues to decline, your Microsoft 365 administrator may need to review the room configuration via Microsoft 365 Admin Center > Resources > Rooms & Equipment > Select and review the room

3/ Check Booking Permissions

Some rooms are configured to:

• Require approval
• Allow bookings only from specific users or departments
• Require delegate approval

If any of these policies apply, the room may automatically decline your request.

Please ask your IT administrator to confirm:

• Whether you have permission to book this room
• Whether the room requires approval before confirmation

4/ Verify Time Zone Settings

In some cases, the room appears “unavailable” because the meeting is being scheduled outside working hours due to an incorrect time zone setting.

In Outlook, if the selected time appears in gray instead of white, it may indicate that it falls outside working hours. Please verify your Outlook time zone settings and adjust them if necessary.

I hope this information helps. If you have any additional questions, please feel free to let me know.
