outlook OST files -- why? RRS feed

  • Question

  • I am aware that in v. 2 OST files are no longer backed up...... but I am wondering why?  I run outlook 2007 and utilize a shared exchange service and thus have an outlook.ost and an outlook.pst file.  I would like both backed up..... why was this ability taken away?  Is there any work around?

  • There really is no reason to back up an .ost file as it is, by design, an offline version of the data that is on Exchange and will be synchronized when you are connected with the server. It is, in effect, a temp file, to read your data when not connected with the server.

    The only workaround that I can see is to periodically zip the .ost file into an archive, which will be backed up if you select the file type "other" and locate it in a folder that is scanned for new/changed files to back up.
