Office 2010 issue with creating conference room appointments

Question
-
Dear Outlook 2010 gurus:
I am having issues with creating appointments for a conference room in Outlook 2010. We are migrating all of our production PCs from Office 2007 to Office 2010 as we roll out Windows 7 to the company, and one of our first users of Outlook 2010 noticed that when he invites a conference room in a calendar appointment for a time-slot that has already been booked, the request goes through at first but he immediately gets an email from the conference room account declining the appointment because the time is not free. The response has the following text:
"Your request was declined because there are conflicts."
In Outlook 2007, however, whenever somebody attempted to book an appointment with a conference room that already had that time filled would get the following response:
"<such-and-such-a-resource> is already booked for the specified time. You must use another time or find another resource."
Why is this a big deal? Because when there are many people invited to a meeting in a conference room, they all get invitations for the conference room even though the conference room declines the appointment because it's already booked. We are currently using Exchange 2007 but will eventually be migrating over to Exchange 2010. Any ideas how to rectify this problem?
Thank you very much for your assistance!
Sincerely,
John K.

Hi,
OK, I would like to describe the issue as “Outlook 2010 unable to detect appointment conflict.”
Could you please try the method?
Modify the following user registry key:
[HKCU]\Software\Microsoft\Office\14.0\Outlook\Options\ConflictMsgClsSet the value as 4.

Hope it will be the solution. You could also go Outlook forum for a question which would be the most relevant forum for your question.

So you want the attendees get the meeting request after the meeting is approved.
As I know, it is impossible for Exchange 2010 and the earlier versions.

That's not exactly what I'm wanting to do. On Windows XP with Outlook 2007, when somebody attempts to book a time-slot with a conference room invited to the meeting, if the conference room is not available at the time, a windows immediately pops up and says "<such-and-such-a-resource> is already booked for the specified time. You must use another time or find another resource." The appointment can't even be created if the conference room isn't available. On Windows 7 with Outlook 2010, however, the appointment does get created and all the invitees are sent invitations, but the conference room sends a declined reply (if the time slot is filled). Meaning that all the other users can accept the appointment, but they won't have a place to have their meeting because the conference room has declined the appointment.

It seems strange.
I think it has nothing to do with Outlook version, such similar issue always caused by the room mailbox configuration.
What’s the version of Exchange server?
I assume you are using Exchange 2010, I suggest you check the following options:
1. Resource policy
Uncheck “Allow conflicting meeting requests”
2. Resource General
Enable the resource booking attendant.
Managing Resource Mailboxes and Scheduling

I don't see how it cannot be related to the Outlook version - using the exact same username on the exact same Exchange server, we get different results while booking calendar appointments on Outlook 2007 than we do when booking the same calendar appointments on Outlook 2010. The only other variable is that the Outlook 2007 installations are on Windows XP PCs and the Outlook 2010 installations are on Windows 7 PCs, but the version of Windows should have nothing to do with calendar appointments are booked in either version of Outlook.
We are currently using Exchange 2007 but plan to move to Exchange 2010 as soon as we finish rolling out Windows 7 to our company. Per some online searching that I did, it appears that I am not alone in this issue:
Thank you for your time.

Any chance you found a resolution for this issue? We are experiencing an identical problem with Outlook 2010 in an Exchange 07 environment. Did the registry key setting have this message pop up in Outlook 2010?
If you can shed any light on this I would really appreciate it.
Thank you,Anthony G.

Hi,
This did not work for me?
I have the exact same issue. Outlook
2007 responds correctly with "<resource> is already booked for the
specified time. You must use another time or find another
resource."
Outlook 2010 does not?
It is client side issue most
certaintly.
The steps I took to attempt this fix.
Opened regedit
and browsed to the following user registry
key:
[HKCU]\Software\Microsoft\Office\14.0\Outlook\Options\
Do not see
'ConflictMsgCls' pre configured?
Assumed it is a 'DWORD (32-bit) Value'
and created with a value of 4.
Rebooted the machine.
Tested. I
still receive the decline email reply as oppossed to the pre-send
decline.
This seems like a real backwards step in Outlook 2010.
Any other suggestions?Friday, December 9, 2011 12:08 AM -
Hi,
I faced issues while booking an resource which was configured to be booked automatically. I found solution on the following link
http://support.microsoft.com/kb/982774
Summarizing the solution for quick reference -
- Exit Outlook.
- Start Registry Editor.
- Locate and then select the following subkey in the registry: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Options\Calendar
- On the Edit menu, point to New, and then click DWORD Value.
- Type EnableDirectBooking, and then press ENTER.
- Right-click EnableDirectBooking, and then click Modify.
- In the Value data box, type 1, and then click OK.
- Exit Registry Editor.
- Start Outlook.
I hope this helps.

This did not work for me. I've opened a paid support case so hopefully I will get a definitive answer and will post here. I have tried everything in this forum. Outlook registry changes, AutoProcessing commands, etc. and nothing has been able to bring back the pop-up alert "'RoomX' is already booked for the specified time. You must use another time or find another resource."
I understand that the organizer should manage the meeting, but why take away this functionality?
I am running Exchange 2010 SP2 Rollup5 and clients are Outlook 2010.
Anyone found a definitive answer on this yet?
