Hello. I've been running Exchange 2003 on a virtual windows server 2003 machine for many years (currently using VirtualBox) and on Tuesday in ended up with a corrupt message store (priv.edb). I think this may have been caused by a forced power off. I had a backup of the VM (the entire machine) from the previous Friday, so I reverted to this, knowing that I'd lose any emails from between Friday and Tuesday. The reverted machine worked fine and I thought all was well. However I've been noticing some very odd behavior. On my two Outlook 2010 clients I use cached mode. I've seen popups showing emails arriving, but when I browse to my inbox they're not there. But this only happens for some emails, not all. On my iPhone I've checked my inbox and seen new mails, then I refresh the inbox and they disappear. Again this only happens to some emails. If I connect to exchange using OWA (or Outlook with caching turned off) I see all the mails, including those which went missing. I've tried re-creating the OST cache file on one of the Outlook clients and it hasn't helped - There are still mails missing from the inbox. Something is clearly wrong and I know very little about exchange so am concerned... Any ideas?

Hi BenCook, "On my two Outlook 2010 clients I use cached mode" Do you mean only two users have the issue? Please also try to re-create the Outlook Profile: Control Panel->Mail->Show Profiles...->Remove Or configurate the Outlook for 2 users on another working client to test.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hi Frank. Sorry for the delay in responding. No, I meant that I personally have two machines both with Outlook installed, both using the same mailbox. I recreated the Outlook profiles on both machines just after I was seeing issues. I did then have a few emails go missing, but in the last week everything seems to have been OK, so perhaps the problem is resolved. Thanks for your suggestions.
