Nobody likes to see an error message on their computer when they go to start their day, especially when they’re launching Microsoft Outlook to catch up on all their email. It’s difficult enough for most of us to get through all our email messages, keep the SPAM to a minimum, and still have a productive day. The last thing any of us wants is for Outlook to refuse to open. Even worse, the error message reported by Outlook is often cryptic and meaningless to the average individual.
Now, it isn’t my intent to scare you with a big list of error messages. However, the following are just some of the errors that you might find yourself faced with some day. If one of these should ever appear to you, keep reading the rest of this article for an understanding of the usual cause of the problem. Here’s that big list of awful errors:
- Client Error: 0x80040600
- Fatal Error: 80040900

Having researched many of these, I can tell you that they almost always point to a problem with the .pst file that Outlook uses to store all of your emails, contacts, calendars, etc. You see, Outlook stores everything you care about in one big file (it’s actually a database under the covers) that ends in a .pst extension (the file is usually named “Outlook.pst”). And if anything bad happens to it, Outlook can’t open the file and make sense of it, resulting in one of these error messages.
Now, before you panic, there are three possible ways to get back up and running. First, see if you have a recent backup of your Outlook.pst file that you can restore. Second, try the free repair tool provided by Microsoft called ScanPST. Unfortunately, ScanPST is rather weak and can’t fix all Outlook corruption problems. So there are a few third party tools on the market that do a more extensive job of recovering and repairing PST files. Search for “PST Repair” and look for a tool that lets you download a free trial version that you can run on your own file as a test. And, finally, it probably won’t hurt to keep your fingers crossed.
