I have never been able to get the indexing to work in Outlook 2007 that is connecting to my Exchange server. I started with the WDS 3.0Beta Preview before Beta 2 was released and had no luck. Now that WDS Beta 2 is out I removed the previous version and installed Beta 2. Tried to force the index to run by rebuilding it and still couldn't get search to work for any exchange mail. Waited a couple of day's thinking it may just need time, still no luck. It has indexed the mailbox that is setup for my personal mail (POP3) which is a .PST file. When I go to the indexing options and click on Outlook and then click modify I get the following pop up.
---------------------------
Microsoft Outlook Offline Folders
---------------------------
The file C:\Documents and Settings\rsbomar\Local Settings\Application Data\Microsoft\Outlook\outlook.ost is not compatible with this version of the Personal Folders information service. Contact your administrator.
---------------------------
OK

I've tried deleting my profile and deleting the .OST file and recreating my profile all with no luck.
Any suggestions

Paul,
Do you have more information on how to enable searching via the group policy
I am just curious, any idea what the reasoning was for changing this feature from version 2.x to version 3 Version 2.x I didn't have to run in cached mode or set a policy and it searched my mailbox.
Thank you!

rsbomar,
It sounds like you are using an uncached exchange mailbox. There are two ways to fix this. First, you could set your Outlook to operate in cached exchange mode. Second, you could leave your mailbox as-is and ask your administrator to enable the indexing of uncahced exchange mailboxes via group policy.
