Sometimes it so happens that when you click on any Hyperlink in an Outlook email, you get an error message which goes like this:
This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.
This error is actually not an Outlook error. Your Outlook configuration is alright, but you need to go and fix something outside Outlook to get this working. This error occurs when a specific part of the Windows Registry related to Internet Explorer settings is corrupted or missing. This can happen if you upgraded the version of your IE.
There are a couple of approaches you can take to resolve this:
Try the simple way first
Instead of diving into the registry right away, we can try and reset the settings in Internet Explorer. Depending on the version of your IE, there are different steps for this.
Internet Explorer 6
- After running IE, go to the Tools menu and click Internet Options.
- Click on the Programs tab and then click the Reset Web Settings button.
- Under Internet programs, verify that the correct e-mail program is selected.
- Select the “Internet Explorer should check to see whether it is the default browser” check box.
- Click Apply, and then click OK.
Internet Explorer 7
- After running IE, go to the Tools menu, click Internet Options.
- Go to the Advanced tab, and then click Reset.
- Go to the Programs tab, and then click Set programs.
- Click Set Default Programs.
- Click to select Microsoft Outlook, and then click Set this program as default, and click OK, and then close the Default Programs dialog box.
- On the Programs tab, click Make default under Default web browser and click OK.
Now, this may or may not work to resolve your issue. If your problem still persists, then read on.

To fix this, you need to export this key from another computer, and then import it into your own registry. Before you proceed, I have exported this key from my computer and made it available for download. If you trust this site (no reason for why you shouldn’t) then you can download the key and use that (it will save you the hassle of exporting). Here’s the download:

Importing the registry key
To import the registry key, you have to carry out two very simple steps:

That’s it, you are done. This should have fixed your problem. If the problem still persists, then please let us know. We will do our best to help you resolve it.
