To create a new pst file:
-File-> New-> Outlook Data File…
-When prompted (Outlook 2003 and 2007 only), select "Office Outlook Personal Folders File (.pst)" and click OK
-Choose the location where you want file to be placed (you can rename the file if you like) and click OK
-You can change the display name if you like (this is the name you see in Outlook, it does not have to match the file name) and you may also set a password on the file (usually not needed, unless you want to restrict access to it). Make sure you do not lose the password if you set it, or you will be unable to access the email stored in the PST file. Click OK
To move all data to the new pst file:
-Switch to the Folder List Navigation (CTRL+6). This will make it easier to also copy your Calendar, Contacts, Journal Tasks and Notes folders.
-Now copy all the folders from the ANSI pst-file to the newly created UNICODE pst-file. You can do this by drag & drop but since the default drag & drop with the left mouse button is a "Move" action instead of a "Copy" action you must use drag & drop with the right mouse button. Now when you drop the folder, you’ll get a pop-up menu allowing you to choose to Copy the folder. This copy also copies all the subfolders.
**Depending on the size and the amount of folders and items in your pst-file, this copy action can take quite a while. During this, Outlook could appear to be in a non-responsive state while in fact it is not. A good way to see if Outlook really is not responding anymore is by going to the location of your newly created UNICODE pst-file. Look at the file size and refresh your view every few minutes by pressing F5. If it is still increasing, Outlook is still running as it should.
-To switch back to the default view (Mail View) press CTRL+1
To deliver new emails to your new pst file:
File-> Data File Management…-> select your newly created pst-file-> click "Set as Default"-> click "Close"-> Restart Outlook
To disconnect the old pst file:
Now that everything has been converted and configured properly, you can disconnect the ANSI formatted pst-file from Outlook so it does not show up in your folder list. You can do this by selecting the file in the data files overview of Outlook and pressing the Remove button.
File-> Data File Management…-> select your old ANSI pst-file-> click Remove
When you now close Outlook, you can actually delete the old ANSI formatted pst-file as well to free up some space if you would like. Do not delete the file before disconnecting it from Outlook.
