OAB in Exchange?

Posted on 2009-07-12
Last Modified: 2012-05-07
I am using exchange server 2007 and I have outlook clients using 2003 and 2007. I would like to turn the syncing of the offline address book off and cannot seem to do it. Could someone explain to me how this is done from the server side.

If Outlook is running in Cached Exchange Mode, it will automatically sync the Offline Address Book. Period.
If you want to stop the OAB syncing, clients will need to run in "online" (i.e. not Cached) mode on Outlook. They will then run a direct connection to the server and thus will not sync the OAB.

So you don't want your Outloo kusers to download OAB . the only options options is to do sois that you give the Deny permission on the oAB object on the exchange 2007 users.

The link Npatang has referred to simply reiterates the same question I am asking: Why would you want to?
If users are still in cached mode but you stop them downloading the OAB, their local address list would become so out-of-date it would become unusable. The OAB forms an integral part of using Outlook offline.
If you want to stop users using Outlook offline, turn off cached mode - rather than using a clunky workaround which is probably unsupported and will have unknown consequences.

basicaly our current setup has our wireless users not connecting properly I took your advise and took them off cached mode and it works like a charm.  This was the answer I was looking for just didn't know how to ask :)
