Outlook Express Errors

Understanding Outlook Express Errors

Outlook Express is the Internet e-mail and news reader that is included as a standard component in the Windows operating system of your PC.

Although it bears a very similar name to Microsoft Outlook, Express simply does not carry the  task and contact management abilities of MO, nor does it handle e-mail other than normal internet mail. Whereas Outlook has an in-built diary and organizer capabilities, for example, Outlook Express does not.

So, you might view it as simpler tool than Outlook, which is to a certain extent true.

That does not, however, mean that it never suffers any problems! Indeed, like every other program that is a part of the Windows operating system, every time you open Express, you are likely to be causing problems of some nature to occur!

What Kind Of Errors Occur In Outlook Express?

As we established above, Express is a program that is designed to do relatively few jobs, that is, email and newsgroups.

Thus, the problems and errors that occur with Express are likely to mean that you either cannot send or receive emails and newsgroup bulletins.

Here is a small list of possible error codes:


In fact, it is really only a question of the degree of impaired functionality that will give you a clue to the root cause of the problem, in most cases.

For example, if Express is running slowly, then there is likely to be a problem, most probably a damaged or corrupt imagehlp.dll within the Windows registry. This would be on the basis that Express is very slow, but that everything else (in particular, Internet Explorer) is running normally.

If, on the other hand, both Outlook Express and Windows Explorer are slow to start, then that is probably indicative of a different problem

This situation is more than caused by missing or corrupt settings or files in a Windows service that allows you to save passwords known as the Protected Storage Service.

An overfull or bloated folders.dbx file would most likely case Express to be anything other than Express, slowing down to a crawl in every task that it attempts to handle.

So, analyzing problems in Outlook Express is first and foremost a question of accurately assessing the ‘symptoms’ of the problem, in order to decide what the root cause might be.

The problem with this, of course, is that it assumes that your Windows operating system is going to go out of its way to co-operate with you to the fullest, which it doesn’t do!

In reality, individual problems do not appear in isolation.

More than likely, once one error occurs, it will cause others to occur and then appear as well, most likely all at the same time.

Thus, whilst, in theory it is relatively easy to isolate errors in Outlook Express, it is actually likely to be more difficult than it might at first appear, in practice.

How To Fix Outlook Express Errors

As will most likely be obvious from the comments above, the major problem that you will have if you want to repair any errors that might occur in Outlook Express, is going to be isolating what those problems really are.

Although, in theory, it might be as easy as ‘if this happens, then that is the cause’ to discover what is causing Express to run slowly or cease to function altogether, in practice, that is just not the way things work in the registry system of any Windows PC.

All actions and reactions within Windows are interdependent on one another and so, once things do appear to be going wrong, there are already a multitude of files and folders all working together to cause your difficulties.

In this situation, only a true expert can realistically hope to repair Express manually, by isolating the malfunctioning individual elements of the registry and then repairing or replacing them, one by one.

Plus, it would be an incredibly time consuming task to attempt as well.

For all of these reasons, as soon as you suspect that there may be some problems or errors within Outlook Express on your PC, the first thing to do is to run a fee scan with a program such as SpeedyPC, to uncover what problems really exist.

The chances are that you will be very surprised at just how many errors such a scan will bring to the fore!

Then, rather than wasting time and effort trying to fix the highlighted problems manually, or risking casing even more damage to the registry of the PC use the software to fix whatever problems were highlighted.

Simple, quick and you will know that the job has been done correctly.

    An unknown error has occurred. Account: ‘pop.earthlink.net’, Server: ‘pop.earthlink.net’, Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800C0133

    I’ve been getting the above message in my Outlook Express for a few days. This message appears when I press ‘send/receive’. I copied and pasted the message into a Google search and your RegCure website came up as the first link in the search which I clicked on and it gave the above error number, saying: guaranteed to fix the problem in two minutes. So I purchased, downloaded/registered etc. your product. Ran the scan, ran the fix errors, but the problem continues to occur. Am I doing something wrong?

    Thank you,

    To Robert Zuckerman,
    Did you ever find out the answer to your problem?. The very same thing happened to our PC & we can’t figure out how to fix it. If you read this I hope you’ve found the answer & will let me know. Also, all our emails are gone and we can’t get any emails in our “Inbox”. Extremely frustrating!

    we have three identities that we use in Outlook Express.
    sometimes, when switching between identities, the Outlook software locks up – it disappears – the only way we can get it back is to close everything and restart the computer.
    do you know what is causing this?
