Environment:Exchange 2003 Ent. Cluster (3 Act. 1 Pass.)Hi,No matter how much training we provide, people are still booking resources incorrectly causing meeting rooms to be double booked. We have users that properly add the room as a resource and then others that add the room as just an invitee.Is there anyway to prevent users from picking a resource as an invitee?

To quote Ed Crowley: "There are seldom good technological solutions to behavioral problems." :-)Seriously, if the user is using the Free/Busy feature of Outlook and they can see that the room is booked, then they really deserve to get a rejection notice or a double-booked room. :-) This is almost the same as if you had a paper calendar for room usage and a second person ignores that someone else has written on the calendar that they are booking a room. Have you considered implementing a 3rd party solution for resource booking such as Simpler-Webb's Exchange Resource Manager. I am assuming that you are simply giving your users the rights to add things to the calendar currently. Jim McBee - Blog - http://mostlyexchange.blogspot.com

You may want to give Auto Accept Agent a try. The agent checks the availability by looking at the calendar (resource schedule), not the Free/Busy information. This reduces the number of issues caused by free/busy update lag Exchange 2003 Auto Accept Agent vs. direct booking Understanding Auto Accept Agent

If you plan on going to Exchange 2007, then Exchange 2007 has an improved Auto Accept agent built in.lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com

So, when booking the resource, userA selects the resource and adds it to the To: Field while userB does it correctly and adds it to the resources: field. Are you suggesting that 3rd party products prevent this?
