Outlook 2007 Crashing for no reason

Can anyone help? (Please don't tell me to reinstall everything, because that isn't a fix)

Good Morning Marty,
What is the size of your PST?  Have you tried running the Detect and Repair tool?  I can understand your frustration, however, to say that reinstalling an application is not a fix is an incorrect statement in my opinion.  The dll error indicates some corruption, and in a lot of instances reinstalling an application is absolutely the correct fix to a problem.  

In any case, I'd recommend running Detect and Repair, making sure you are up to date with service pack 2 and all Office Updates.  Another option is to re-create your Outlook profile.  Lastly, I'd recommend running a Malwarebytes and ESET Online scan to make sure your system is not infected.

Start your 7-day free trial
try starting outlook with the /noextensions switch
Hmmm, try re-installing Outlook Express as per: http://support.microsoft.com/kb/290782

which I know is for Outlook 2000, but it is worth a shot.

Install SP2 for Outlook 2007 which will install a later version of that DLL.
my version is 12.0.6514.5000
I would try it in this order:
1.) Install Office 2007 SP2
2.) If 1. fails then try outlook /noextensions
3.) if 2. fails then re-install Outlook express

Some good suggestions, I shall try them in the morning.

I've tried detect and repair, and also scanpst and opening in safemode all to no avail.

Doesn't SP2 auto install with updates?
It will only install if it is allowed, most computers only look for Windows Updates by default, not office updates.

Hi Marty,

In order to get Office updates via the Automatic Updates service, you will need to upgrade to Microsoft Update: go to: http://office.microsoft.com/en-us/downloads/FX101321101033.aspx?pid=CL100570421033 --> Downloads and select Microsoft Update on the left panel under Updates.

You can download Malwarebytes from here: http://www.malwarebytes.org/mbam.php.  Make sure to run the update.  ESET Online scanner can be accessed from here: http://www.eset.com/online-scanner.

Take care,

I wanted to also add that if you can pinpoint the day when Outlook started crashing, you can run a System Restore from a day or two earlier.
SP2 for Office 2007 should resolve this for you. You are probably better off downloading it from microsoft's download website and then extracting it and burning it to a CD and keeping it on a network location for future use.
I usually find that a chkdsk, sfc /scannow and/or install sp2 fixes it
Lacretta IncorvaiaCommented:
I agree that SP2 can be the resolution, which is why I recommended it in my very first post.  I only mention scanning for malicious content, because that can very much corrupt dlls.
