This is the desperate cry of someone who is about to panic. They have emails from 1995 and about 1,000 contacts, and now that is in jeopardy. Here are a few things to try. The first would be to utilize the Inbox Repair Tool. This is easy to do. You may or may not have the Inbox Repair Tool on your computer. One quick way to find out is to click on Start>Run, then type scanpst.exe in the open box, then click “Ok”. If the Inbox Repair Tool starts, you have it installed – if not, then you have to go download it here. Now, we need to repair your .pst file…
You need to locate your .pst file. It can be found at C:\Documents and Settings\USER_NAME\ Local Settings\Application Data\Microsoft\ Outlook\ , where “User_Name” is your login name. Open the Inbox Repair Tool and browse to your .pst location. Now, click on “Start”. Hopefully, this will solve the issue for you.
But, if you end up with “Fatal Error: 80040900″, then you probably have exceeded the 2GB limit on your .pst file. Yes, there is a maximum size to it. Go here to solve this issue.

Why anyone would keep 2 gigs of mail is beyond me, but with Outlook 2003, I’ve seen PSTs larger than 8 gigabytes.
I’ve got mail at home from 1996, and only about 150 megabytes, but then again, I strip out most attachments, if they are worth while, they are saved as individual files on my hard drive, easier to back up.
I would rename the pst file to something like outlookold.pst and then start up Outlook again – it will automatically start a new pst file. Then I would import the contacts list from the old file and any relevant folders or emails. The rest I’d leave. Have done this a few times for clients and myself – works well.
Where is fine tool-outlook express inbox repair tool, recover lost messages from corrupted Outlook Express folders, recover corrupted Outlook Express folders (.dbx files), the DBX extractor undelete messages permanently deleted by accident from the Deleted items folder, the DBX extractor export correspondence to the eml format (a common format for mail messages) and move message to another computer, read and view information stored in .dbx and .dbt files (including corrupted dbx files).
