I have several users running Windows XP SP2 and Outlook 2003. They save many of their e-mails to a network drive. When they save these e-mails, they first change the subject line (or the name of the file) and then save it as a .msg file to a network drive. After they have saved numerous e-mail successfully, they will inevitably receive the error "not enough storage is available to process this command" when trying to save these files to a network drive. At that point, they cannot save anymore e-mails until they reboot their machine. Does anyone know what the fix is for this error?
