Outlook Pst Repair - Tips To Solve Thorconnwndclass Error In Ms Outlook

The earlier versions of Norton System Works included a component called ThorConnWndClass as a part of 'Crash Guard' Symantec

. This component can cause several issues especially when you are running MS Outlook. It can cause Outlook to hang unexpectedly and result several ThorConnWndClass errors. However, in some cases, the same problem can also root from other issues like corruption of Outlook PST, which is curable through Outlook PST Repair solutions. If PST is corrupt, you can try solutions like running Inbox Repair Tool and restoring from backup.

As an instance of such problems, consider you try to send or receive an email in MS Outlook. The process ceases and you receive few errors, such as below:

Outlook freezes and you need to close the application forcefully. The similar behavior may also be observed when viewing the contents of mail folders or performing any other email function.

Some of the possible reasons of this problem are:

1-ThorConnWndClass of Norton System Works

2-Damaged Outlook bar

3-Corrupted Outlook add-ins

4-Corrupted Outlook settings

5-Issues in Outlook installation

6-Corrupt email(s) on server or damaged Outlook Personal Folder

Solution

You can try these solutions to overcome the existing issue:

1-If Norton System Works is installed, uninstall it manually. This most of the times resolves the issue.

2-Recreate the Outlook bar using /ResetOutlookBar switch.

3-Unload the installed Outlook add-ins. Click Tools | Options | Other tab | Advanced | Add-in Manager. If this works, you can later try reloading these add-ins one at a time.

4-To correct Outlook settings issue, you can rename outcmd.dat and extend.dat files after closing the application.
