Hi Guys.

I am running sbs 2003 with Outlook 2003 clients in Cached Mode, a user with a POP3 account being delivered to his mailbox was working Offline when Outlook displayed a Send error and then closed, upon reopening Outlook his View had changed and emails that were just downloaded had disappeared. The .ost file appears not to contain the missing emails. I need to recover these emails if possible and determine what happened for future reference.

Thanks for any suggestions

Try turning cache mode off and see if they reappear.  Cache mode should not be downloading mail, but you may want to check for PST's on the machine and see if delivery is set to the PST.

For recovering mail, you may also want to look at the DumpsterAlwaysOn registry key.  It's primarilly for recovering deleted mail, but I've used it often to recover mail that has been moved.  After all, a move is just a copy and delete.

Quick response, I like it..the mail was downloaded using the external POP3 account, I have confirmed all accounts (2) are being delivered to his mailbox, the client insists they had not changed any settings but I think I will create a new profile and import the .pst that is present, It's worth a try.

The DumpsterAlwaysOn registry edit is good advice and something that I will implement on all clients.

My apologies.  We are using exchange 2003 and I momentarilly forgot about POP accounts.  We aren't enabling pop but we do use OWA for external access.
