We have several laptop users who are in the office infrequently throughout the week. All laptops have domain membership with roaming profiles and offline file synchronization active. This way, their profiles and data are synchronized with a server during logon/logoff. But offline file synch doesn’t let you target files like Outlook’s .PST file because of the nature of the file. I want to automate the backup of their .PST files so that backup happens during logon but that this doesn’t interfere with Offline Synch tasks. I would like it to be transparent to the end user and silently fail if they are logging on outside of the network.
