Outlook 2007/Exchange 2007 Cached Mode and OAB update

I know there is a lot of posts on how to force an offline address book update either from exchange console or from outlook. Is there a way or setting in Outlook 2007 to keep the user in cache mode but not use the Offline Address book but use the online GAL?

No. The whole point in cached is that you have a local OST and OAB.

Check http://www.howexchangeworks.com/2009/08/how-offline-address-book-works-in.html for more info on how OAB works.
No it is not possible
Yes, there is a way, let me find it and hopefully post back soon.

But if your user goes offline they will have no access to the GAL/OAB. Wouldn't you rather get the OAB download working?
Free recovery tool for Microsoft Active Directory

Veeam Explorer for Microsoft Active Directory provides fast and reliable object-level recovery for Active Directory from a single-pass, agentless backup or storage snapshot — without the need to restore an entire virtual machine or use third-party tools.

Here you go:

Delete the .OAB files on the Client machine and set the reg entry mentioned above to 0

MegaNuk3 that works like a champ, I just have to make sure I script out a kill process that shuts down outlook so it can delete the .oab files.  thanks for the help. I tested and it works great and doesn't create new .oab files it uses the online GAL
Thanks for the update and the points.
