Any IT pro within the last decade will tell you to learn how to deal with PST files. Even though they're portable, they seem to be easily compromised. Before we get into that, let's go over basic Outlook 2003 PST management.

To Find Folder Sizes in Outlook

1. Right mouse click on Mailbox – Your name

2. Click on Properties for “Mailbox – Your name”…

Mailbox Properties

3. Click on the Folder Size… button

Folder Size

4. Outlook will read your mailbox to determine the size of the subfolders

5. From here you’ll be able to determine which folders need to be cleaned by either moving the data to a Personal Folder (.PST) or by deleting old data that’s no longer needed

6. The sizes are listed in kilobytes (KB). There are approximately 1,000 KB in 1 MB (megabyte). As we can see from the example shown below, the mailbox is approximately 17 MB

7. The Deleted Items folder should be emptied every time Outlook shuts down (this should be done automatically)

8. The Inbox and Sent Items folder should be cleaned periodically, either by deleting the mail or by moving the files to your .PST
