Outlook 2007 moving ost file to different location

Luckily, it's not too difficult to move the OST from the default location to anywhere you want it
Refer to the picture above, and follow the simple steps (don't forget to restart Outlook when prompted)...
1. Go into Tools | Account Settings
2. [A] On the Data Files tab select the data file for the account
3. [B] Turn off "Cached mode" on the "advanced" tab
4. [C] Disable "Offline use" on the "offline folder" settings popup
5. And then.... you can move the .ost (in Explorer) and reference the new location to have Outlook work with it
6. When you've finished don't forget to re-enable "Offline use" and turn "Cached mode" back on - otherwise you'll only be able to work when connected to the remote server
When you have finished this process Outlook may spend a moment re-synchronising your local data with the server, but if you have moved and used a recent OST then the process will be no longer than a normal send/receive.
