Trying to open a hyperlink in Microsoft Office Outlook - you recieve the following error message and subsequently cannot open the hyperlinks:

This operation has been cancelled due to restrictions in effect on this computer.

Cause: Upgrading Internet Explorer from a previous version or uninstalling Google Chrome can corrupt dependent registry keys.

Following the simple steps below will help fix the issue:

1. Reset Internet Explorer settings to default and retest. If this does not work move on to step 2.

2. Set Internet Explorer as your default Browser - restart & retest - if no dice then move to step 3.

3. Open a Command prompt as Administrador on Windows Vista or Windows 7. Then copy and paste the following info line by line - pressing the enter key on your keyboard to initialise each command:

REG ADD HKEY_CURRENT_USER\Software\Classes\.htm /ve /d htmlfile /f

REG ADD HKEY_CURRENT_USER\Software\Classes\.html /ve /d htmlfile /f

REG ADD HKEY_CURRENT_USER\Software\Classes\.shtml /ve /d htmlfile /f

REG ADD HKEY_CURRENT_USER\Software\Classes\.xht /ve /d htmlfile /f

REG ADD HKEY_CURRENT_USER\Software\Classes\.xhtml /ve /d htmlfile /f

After trying options from other sites unsuccessfully, I finally tried the registry commands above and it worked! Thank you very much :)

Wow - it worked! I've been trying everything the last few days and getting advice from other sites - including changing the registry etc. But the registry command options you listed worked a treat.
Thank you sooooo much.

The 3rd step worked like a charm! Thanks! This was driving me nuts for days!

By Kara on   Fri, 23 Nov 2012 04:09:26 GMT

Well, good for all the rest of you because NONE of these steps worked for me! Not even the manual registry key entries, and I double-checked to make sure they existed after copy/pasting them into a command prompt. (Yes, I opened it as Administrator.)

Restarted IE. FAIL- Still the same error.
Restarted the computer. FAIL - Still the same error.

Complete waste of time.

Worked for me too. I was stumped. At first I thought step 3 didn't work for me, but I rebooted, tried the links again, and SCORE!

Having problem with links "This operation has been canceled due to restrictions in effect on this computer" with Outlook 2007 and IE 11 as default browser I just make Chrome as default browser an then again IE as default browswr. The problem with links in Outlook vanished.
