1] Relocate PST and OST files to Dropbox

If you use Dropbox or OneDrive, I suggest you move the PST file of your Outlook Profile to one of your DropBox Folders, which you do not share with anybody. On top, you can use the same folder with any other computer, ensuring you have the same data access when you go from Office to Home or switch between computers.

  1. Once Outlook is launched, first find out the location of the PST or OST file of the profile you want to move to Dropbox.
  2. Go to File > Account Settings
  3. Select the Data Files Tab; you should see all PST or OST file locations.
  4. Now make a list of the emails and their PST file.
  5. Close Outlook.
  6. Next, Go to Dropbox, Create a Folder named Outlook Data, and Move All those PST and OST files. Notice I said move, so make sure you do not have a copyleft on that folder.
  7. Next, Launch Outlook will prompt for missing PST files which you can browse and locate.
  8. That’s it; you are done. All your files are on Dropbox, which automatically Syncs.

Also, remember that it is possible that the files on Dropbox will not sync as it is used unless you close them. So wait a few minutes before you shut down your computer or close Outlook while on break. Make sure Syncing is not Paused on Dropbox.

The best part of this method is that it works with all versions of Office, including Office 2019 and Office 365. If you want to manually backup PST file, it’s rather easy:

  • Click on File > Open and Export
  • Export to a file > Outlook Data file (.PST)
  • Save it somewhere.
