I have a user who is running Outlook 2010 which connects to an Exchange 2003 server. The user is reporting that he loses emails regularly but can connect to OWA and the email is there. I recently deleted his OST file and recreated the OST file on his computer which seems to work OK for a few days but then he tells me he has lost another email. I have approxamiatley 70 users of this email server and none of them report losing email like this user.
This user is a remote user which connects to the exchange server via VPN but I have also configured his Outlook to pull his emails from the OWA connection when the server or connection is slow which works on all of the remote user mailboxes except for this user. How can I troubleshoot this problem and correct it? I realize that Exchange is at the end of life but I have no other server to go to so I need to use this version.
Thank you in advance.
