Backing up Outlook Data

How do I backup Outlook Data?

Backup Outlook buttonBacking up Outlook is actually a really simple thing to do; just copy the pst-file to your "safe" location.

Ok, this will make you wonder some other things of course in terms of what, where and how.


What? buttonThe pst-file is the main file Outlook will keep its data in; received items, sent items, contacts, appointments, tasks, notes and journal items are all kept in a single file; even your RSS feeds are kept in there! For an overview of what else is kept in a pst-file see: What is lost by exporting/importing pst-files?

Although I said single file, you can of course have multiple pst-files in your configuration like for instance an archive file. So with that said; make sure you backup all your pst-files.

Note: Exchange and accounts sync their data to ost-files. As the “master copy” is stored on the mail server itself, you don’t have to back up ost-files. IMAP accounts in Outlook 2013 and later are a special case though.


Where? buttonBy default the pst-file is kept in the following location;

  • Outlook 2007 and previous (default location)
    • Windows XP
      C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook\
    • Windows Vista, Windows 7, Windows 8 and Windows 10
  • Outlook 2010 (default location)
    • Windows XP
      C:\Documents and Settings\%username%\My Documents\Outlook Files\
    • Windows Vista, Windows 7, Windows 8 and Windows 10
      C:\Users\%username%\Documents\Outlook Files\
  • Outlook 2013, Outlook 2016, Outlook 2019 and Office 365 (default location)
    C:\Users\%username%\Documents\Outlook Files\

Note that these are hidden folders but you can directly cut & paste or type these locations in the Address Bar in Explorer to open these folders.

Another way to see where your pst-files are located, is to open Outlook and choose;

  • Outlook 2007 and previous
    File-> Data File Management…
  • Outlook 2010 / 2013 / 2016 / 2019 / Office 365
    File-> Account Settings-> Account Settings-> tab Data Files


How? buttonNothing special. Once you've located your pst-file you can copy them like any other file. Just make sure Outlook is closed.
