I've created a few resources room in exchange 2007. I can see the rooms when I schedule a meeting but my uses cannot see the rooms when trying to schedule a meeting. They get a error message - "The bookpmark is not valid". Any ideal on how to fix this?

It can be seen as an identified issue and you should update the exchnage server with: Update Rollup 4 for Exchange Server 2007 SP1 (KB952580)Regards from www.windowsadmin.info | www.blog.windowsadmin.info

Hi, It could be a permission issue. Have you ever configured GALSegmentation? Please run this command and post the output: Get-AddressList "All Rooms" | Get-ADPermission | where {$_.ExtendedRights -like "Open-Address-Book"} | ft -AutoSizeMartina Miskovic
