I was led to believe through product documentation on the Acronis web site, Amazon.com, and other places that True Image can back up open files without a problem. However I am getting error msgs that my Outlook .PST file is in use. Worse, the program displays a dialog box for a scheduled job that is running unattended in the middle of the night, and then just pauses, waiting input, instead of ending. This prevents a 2nd scheduled job from running. Can someone help me out? Thanks.
