I am using Outlook 2003 with redirector on Exchange Server. Would anyone know why every 12 hours or so I stop being able to send and receive email. I have to call into the office and ask someone to reboot my computer. Once rebooted and with Outlook and redirector running again, email is working again. The problem is that I have to do this every day. If I try just re-starting Outlook I get an error message saying that my pst. file in unavailable and already in use. Reboot seems to free the pst. file. Any sugestions.
