AFAIK (and I'm not an Exchange expert) you can only open an OST file if you re-create the Exchange Account which created it in the first place, other than buying conversion software...
From: JohnB on 18 Mar 2010 16:08 I had never heard of Xobni, but I just looked at their website. What's the advantage over the Outlook built-in search? She only has 1 Exchange account. The 3 OST files have 3 different date stamps. I was told there should be only one in there. So I am guessing that this happened because offline mode was turned off and back on, and when that happened, a new OST was created? "Leonid S.

From: M on 18 Mar 2010 23:12 I thought you knew what an OST was. It's an OFFLINE copy of a mailbox. If you're disconnected from the network and Outlook is in "offline" mode, it uses the OST exclusively. In "online" mode, the OST is also used, but there's interaction with the Exchange server (syncing and updating in the background). The steps I gave you is an attempt to "trick" Outlook into opening an older OST. When you do what I suggested and (if) Outlook is able to access the OST file, you'll see the contents of the mailbox as it looked when that particular OST file was last sync'd with Exchange. That's why it's important that you perform step 1 to totally disconnect her computer from the network so that the older OST doesn't try to sync with her current mailbox. Please respond back after you try this and let me know if any of this worked. -- Regards, M MCTS, MCSA "JohnB" <jbrigan(a)yahoo.com> wrote in message news:Oa46qctxKHA.5480(a)TK2MSFTNGP06.phx.gbl... > I'll have to schedule a time tomorrow morning to get at her computer. > > Re: Step5 > This is what I don't understand... how do I search or look at the contents > of an OST?

They refused Microsoft's offer to buy them, by the way. M's trick will probably work to fool Outlook into opening those OSTs. I'd make an image of this system before doing anything with it as some changes can render OSTs unreadable due to loss of Exchange authentication token. It's likely that her mail is buried in PSTs and a good indexer would be most helpful there. -- Leonid S.
