Changing the location of OST file - Outlook 2007

Recently, I received a new replacement laptop from Dell (Latitude D620 to Latitude E6400).
So this time, I was setting up dual boot with Windows 2008 R2 RC and Windows 7 RC (both are x64 OS).
 
And I wanted to have a localised OST file to be shared between the two OS. You can easily do that with PST files, but OST file is a bit tricky.
OST file is basically a local Offline Folders file (.ost) when you work offline with Outlook or use Cached Exchange Mode with Microsoft Exchange Server.
The offline folder file has an .ost extension.
 

To change the location of the offline files are saved:

  1. Make sure you have Exited Outlook.
  2. Click Start, and then click Control Panel.
  3. Double-click Mail, and then click E-mail Accounts.
  4. Click View or change existing e-mail accounts, and then click Next.
  5. Select the Microsoft Exchange Server account, and then click Change.
  6. Clear the Use Cached Exchange Mode check box.
  7. Click More Settings.
  8. Click the Advanced tab.
  9. Click Offline Folder File Settings.
  10. Click Disable Offline Use, and then click Yes in the dialog box that appears.
  11. Click Offline Folder File Settings.
  12. Click Browse, go to the location where you want to save your .ost file, and then click Open.
  13. Click OK.
  14. Select the Use Cached Exchange Mode check box.
  15. Click Next, and then click Finish.
