My wife and I use the same desktop with 2 different email accounts in Outllook 2007. About 3 days ago my wife started getting the following message when she tries to click on links in the reading pane:
this operation has been cancelled due to restrictions in effect on this computer. Please contact your systems administrator.



To the best of my knowledge we have not changed any security settings.

This usually happens when the user's profile loses its association with the default internet browser. If you recently installed a different browser (Firefox, Chrome, etc) or set a different browser as the default, this can occur. Try these steps:

1. Open the Control Panel.
2. Open Default Programs (may be listed under the Programs section)
3. Click on "Set your default programs"
4. Click on Internet Explorer in the left pane to highlight it.
5. Click on "Set this program as the default"
6. Click OK.

Now see if she is able to open links. Once she is working properly, she should be able to then change the default to whichever browser she prefers.

Hope this helps.
