I have a remote online backup program on my computer called Connected. I want it to back my outlook .pst file every night. If outlook is closed at the end of each day, does the outlook.pst file that is stored in the .............. have all of your emails in it. Or would you need to manually back it up. I have read different things about this. I also know there is .ost file for offline storage files and an archive .pst. I am assuming that if I backup the entire folder online each night, in case of theft or a failure I would be able get the .pst file from the online backup site and would not lose a thing.
