When you try to click a link in an email message in Microsoft Outlook 2010, 2007, 2003 or XP, you may get the following error:
This operation has been canceled due to restrictions in effect on this computer. Please contact your system administrator.
This problem can be solved most of the time by setting one of your web browsers as the default. Follow these steps:
1. Open Control Panel.
2. Select Programs.
2. Choose Set program access and computer defaults.
3. In the Custom section, choose your preferred web browser, then click OK.
Now open Outlook and try to click on a hyperlink to see if you get the “This operation has been canceled due to restrictions in effect on this computer” error message.
