I've got a user running XP Pro, sp3 with Outlook 2003. The user can't save attachments from outlook directly to a network share. When he tries, outlook gives a message saying the file already exists and asks if he wants to overwrite. The file doesn't already exist. If he selects "yes" to overwrite, he gets an error that he can't save because the directory is read only. The directory is not read only.
He can save the attachment to his desktop, and then from there, drop it in this network share - but he can't do so from outlook where other users with the same software and same directory / AD permissions / groups can do so. Any ideas?
