How to Repair Outlook Express Files

1. Click on the 'Start' menu and choose 'Restart' from the shutdown options to restart your computer. After your computer restarts, open Outlook Express to see if the problem is fixed. If not, continue to the next step.
2. Quit all problems except Internet Explorer and Outlook Express. From the 'Tools' menu in Internet Explorer, click 'Internet Options.' Click 'Delete Files' from the 'Temporary Internet files' section. Tick the 'Remove all offline files' box and click 'OK.' If the problem persists, continue to the next step.
3. Click 'File' from the Outlook Express menu bar, then click 'Work Offline.' Click 'Folder List,' then click 'Outlook Express.' At the upper-right corner of the panel for the list, click 'X' to close it. Choose 'Folder' from the 'File' menu. Click 'Compact All Folders' and wait for the program to finish. Continue to the next step if the problem is not fixed.
4. Select 'Run' from the 'Start' menu. Type 'msimn /reg' into the 'Open' box. Click 'OK.' From the 'Tools' menu in Internet Explorer, click 'Options.' Select the tab labeled 'Programs' in the pop-up window. Set Outlook Express as your default program for email and news. Go to the next step if Outlook Express is still having problems.
5. Select 'Run' from the 'Start' menu. Type 'regsvr32 urlmon.dll' into the 'Open' box. Click 'OK.' Do the same for 'regsvr32 mshtml.dll,' 'regsvr32 shdocvw.dll,' 'regsvr32 browseui.dll' and 'regsvr32 msjava.dll.' If this does not stop the problem, go to the next step.
6. Download the appropriate version of Internet Explorer you are using from Microsoft's site (see Resources). Follow the instructions to reinstall.
