1] Relocate PST and OST files to Dropbox

If you use Dropbox or OeDrive, I will suggest you move your 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, which makes sure you have the same data access when you go from Office to Home or when you switch between computers.

  2. Go to File > Account Settings
  3. Select Data Files Tab, and you should see all the 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 and it will prompt for missing PST files which you can browse and locate it.
  8. Thats it, you are done. All your files are on Dropbox, which automatically Syncs.

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