Hi,

My client is getting a ThorConnWndClass error when she tries to shut down. Supposedly, she goes to "end program" and then the program doesn't respond, etc.

I've been reading about various solutions to this problem, but most seem pretty hard to follow. Is there anyone that can clearly explain to me how to solve this problem without referring me to other links? I've already looked at those and have a lot of trouble following them. That's why I decided to post my own question.

Thank you.

Hi kara334,

The ThorConnWndClass is a component that is shared between Outlook Express and Outlook.
The problem with trouble shooting the ThorConnWndClass error is that a there are many things that can cause it. That's the reason you find so many solutions out on the web. So, the best thing to do is work through the trouble shooting steps starting with the easiest ones first.

The error is mainly caused by two things; something interfering with the inetcomm.dll, (the shared component). When something does, it throws up the ThorConnWndClass error. Or two, Outlook encounters a problem sending and receiving an email because the email is corrupt.

Do the easy stuff first.

1. Disable the addins to see if a third-part app is interfering with the inetcomm.dll.
Start Outlook in Safe mode. The main cause here is the anti virus software.

Click the start button and select Run. Type this in the Run field:
"c:\Program Files\Microsoft Office\Office11\Outlook.exe" /safe

If the above works, disable all the addins by going to Tools ~ Options ~ Other Tab ~  
Advanced Options ~ Addin Manager and uncheck all. Restart Outlook. Check each addin one by one to see which addin is causing the problem.

2. This is more uncommon but easy to check.
The inetcomm.dll may have failed to register. Re-register the dll by following this  procedure.
Click the start button and select Run. Type this in the Run field: Runregsvr32 inetcomm.dll

3. Another common cause of this error is a corrupt email on the server.
There are two ways to solve this issue:
(a). Have your IT run maintenance on the user's mail store on the server. This will rebuild  
the index and hopefully correct the problem with the corrupted email.

(b).If that is not possible or doesn't work, delete the emails on the server up to the point  
where the problem started via webmail or have the administrator do it for you.

4. A stuck message in the outbox. Check your outbox. If you see a message in the outbox, drag it to your drafts folder.

5. Do a repair of Outlook. Click Help ~ Detect and Repair.

6. If that doesn't work, an upgrade or install of Office 2003 usually fixes this problem.  
After uninstalling Office, delete the Microsoft Office folder from C:\Program files and  
reinstall.

Now for the harder steps.

The error could be caused by a corrupted .pst file or the profile.

7. Create a new pst file:
Click Tools ~ Email Accounts ~ View or change existing email accounts ~ Next ~ New Outlook data file and create a new pst file.

8. Create a new profile:

1. Click Start, and then click Control Panel.
2. Double click the mail icon. If you do not see the mail icon, click Switch to Classic  
View.
3. In the Mail Setup dialog box, click Show Profiles.
4. On the General tab, click Prompt for a profile to be used, and then click Add.
5. Type in a name for the new profile in and then click OK.
6. In the E-mail Accounts dialog box, click Add a new e-mail account, and then click Next.
7. Click the appropriate server type for your new e-mail account, and then click Next.
8. Type your account information in the required boxes, and then click Next.
9. Click Finish, and then click OK.

I know it's a lot but, hopefully you will not have to go through every step.
Let us know how you do.

cheers,
frankco
