Have an Exchange 2007 mixed org and using Outlook 2007 as well. I try to keep users in cached mode as much as possible. Now here is what I am noticing though. When in cached mode what is displayed locally does not always seem to be in sync with the server. For instance I do not see anything in my outbox in Outlook but if I go to OWA or take Outlook out of cached mode itmes show up in the outbox and other folders. This is not just on one mailbox but seems to be a config or some other issue. This is a A/P clustered mail server and we have to CA/HT servers as well. Anyone else run across this and of course any idea on how to fix it? Thanks!
