Web Links Don’t Work in Outlook, Word 2007

Several users have reported an issue in which web links (hyperlinks) no longer work in Outlook 2007 and Word 2007. Users experiencing this problem may receive the following error message:

“This operation has been cancelled due to restrictions if effect on this computer. Please contact your system administrator.”

This problem is generally caused by a corrupt Internet Explorer registry key. As such, the first thing you should try is resetting web settings in Internet Explorer. In Internet Exploer, click the Tools menu, click and select Internet Options. In Windows XP, go to the Programs tab, and then click the Reset button. In Windows Vista and Windows 7, click the Advanced tab then select reset. Apply the changes.

If that doesn’t work, you will need to edit the registry, following these steps, as described by Slipstick Systems:

  1. Start, click Run, type Regedit in the Open box, and then click OK.
  2. Browse to HKEY_CURRENT_USER\Software\Classes\.html
  3. Right click the value for the .html key and select Modify…
  4. Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)

Repeat this process for each of the following keys:

  • [HKEY_CURRENT_USER\Software\Classes\.htm]
  • [HKEY_CURRENT_USER\Software\Classes\.html]
  • [HKEY_CURRENT_USER\Software\Classes\.shtml]
  • [HKEY_CURRENT_USER\Software\Classes\.xht]
  • [HKEY_CURRENT_USER\Software\Classes\.xhtml]
