Right now, there's only one email data file. Click picture for a larger image.

You'll need to add a new data file. Click the Add button and you'll see the dialog shown in Figure C.

Select Office Outlook Personal Folders File. As you can see in the dialog, it provides more storage capacity (18GB instead of 2GB). Click OK.

Next, you'll need to find a location for your new PST file. Here's a tip within a tip. I don't like keeping my PST files in the default Documents and Settings folder. It's far too easy to lose the files when upgrading and you often forget to back them up that way. Instead, I tend to put my email PST files in their own My Email folder, as shown in Figure D. You could, of course, also put your new PST file in your My Documents folder. It's all up to you.

Now that you've created the second PST file, it'll show up in the Outlook Data Files dialog, as shown in Figure E.

A side benefit of the new location is that you can differentiate the PST files. Click picture for a larger image.

A side benefit of the new location is that you can differentiate the PST files. While we're on this dialog, note that you can see where mail is delivered. It's sent to the PST file located in Documents and Settings -- for now.

Moving your data
You're now ready to start moving your data. First, I recommend taking a very simple precaution to prevent new email from coming in as you transfer your information. I'm pretty old-school about such stuff, so I simply disconnect my network cable. I figure that if I can see the network cable disconnected, I know for sure I'm not going to be downloading anything (unless, yes, you're using WiFi -- if that's the case, turn off your WiFi).

Launch Outlook and you should see a folder structure similar to what's shown in Figure F. If you look closely at the image, you'll see there are two Personal Folders trees.

A little exploring will show you that the top Personal Folders tree contains all your data and the bottom one is empty. What you're going to do next is copy (not move) your data from the top to the bottom Personal Folders tree.

To do this, click some folders with the right mouse button and drag them down to the lower Personal Folders tree as shown in Figure G.

Make sure you're doing this with the right mouse button. Click picture for a larger image.

You should use the right mouse button because once you release the button, you'll get a little menu, like that shown in Figure H. Select Copy and you'll be copying all your data. Copying is good. We like copying.

Repeat this process with all your folders, including your Calendar, Contacts, and so forth. Once you complete this process, it'll be time to tell Outlook where to deliver mail.
