Running Exchange 2003 SP2 with Outlook 2007 SP2 clients. We are noticing a discrepancy between how online clients and cached mode clients (using OAB) are resolving entries. Accounts are set up in the following typical fashion:Display Name: John SmithExchange Alias: John.SmithSMTP: John.Smith (at) domain.comLogon: ADdomain\SmithJUPN: SmithJ (at)domain.com When Outlook is in Online mode, you can type in the account name (i.e. SmithJ) and it will resolve properly. If we work in cached mode and use the OAB, typing SmithJ does not resolve. I suspect that this is because the OAB isn't capturing all of the attributes (possibly by design). Any insight into this?

Probabaly the OAB is not getting updated properly and timely, so you are not getting the user attributes properly when in cached mode. But as soon as you are going online, you are directly connected to the Ad and hence getting all the user attrib properly.Raj

What is the best way to identify why the OAB is not updating properly? I have already enabled max logging on the OAB and don't see any problems in reviewing the AppLog.

The OAB isn't indexed on account name.---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP
