I have customer who has a new machine running XP with Office 2007 Pro installed.
It has Acronis True Image backup on it and is using the client / agent for Trend Micro(TM) Client Server Security for SMB v3.6 which is running from their server.
For some reason I have been unable to discover, Outlook keeps losing its PST file. I thought I had found the problem when I discovered that the Trend Micro Email Scan plugin was set to delete any file it couldn?t clean. I changed the ?action to take? from ?Delete? to ?Pass? but again a couple of days later Outlook loses its PST file.
So far I have been restoring it from the previous night?s backup of the PST file but I really would like to find the problem. I have Googled this to death and am not finding much on it.
Anyone ever run across this before?
