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

This PC suddenly started to give an error message whenever an outlook email link was clicked:

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

Hovering over the link showed it began with the word: “BLOCKED:”

After some quick research, it seemed the solution was to check outlooks security options:

tools -> options -> security -> Secure content -> Zone

I changed the Zone from “Restricted sites” to “Internet”

Now when I hover over the link, I don’t get the “BLOCKED:” prefix, but clicking on the link still gives the “cancelled due to restrictions” error.

Another poke around the internet gives this suggestion: reset the IE  settings to default… ie:

Tools -> internet options -> advanced -> Reset…

But this didn’t fix the problem either.

Next thing to try was:

Control Panel -> Add/Remove Programs -> set program access and defaults -> at this point, “custom” is normally highlighted… click on “custom -> choose default web browser -> pick the specific web browser you want to use (probably Internet explorer) -> OK

I close IE7, and outlook, restart outlook, and links will now open IE7 when they are clicked on. Hooray!

The customer that had this problem asked if it was possible that a past technician had deliberately caused this problem.

Since I had no way of being sure, I told her so… It would be both a very low thing for a technician to do, and something that required some good knowledge to implement… knowledge that can be used for good instead of evil… but who knows, there are some strange people out there.

    omg, I know what you mean totally.
    I’ve fixed things that I know someone did with intention; but in my heart hoped that as a technician I would never stoop to that level to keep or get rid of a customer.

    such a great post,

    I had same problem after I gave control of my computer to Symantec in order to get rid of a trojan that had got past Norton 360. It took me ages to solve the problem.

    Great Post.
    I have searched, searched, then searched some more to finally arrive here….to find the answer. Who’d thought it would be as simple as redefining my default browser.
    Maybe I can help someone out by listing my affected programs and what i did just prior to all links failing.

    1) I installed Google Chrome (which becomes the default browser without authorization..I might add)

    2) Found out some thimngs didnt work with that browser so I uninstalled it.

    3) Suddenly every link in every Microsoft Program (Outlook, Word, Excel…all of them) stopped working. Kept giving me the “cancelled due to restrictions” error message.

    4) searched and searched for an answer to the problem.

    5)Found this site and did as suggested by resetting my default browser to IE7.

    6) Life is now back to normal.

    Another solution to this if none of the above work (resetting etc), download firefox and install…make it the default and then swap it back. Uninstall firefox.

    I tried a number of things on this including the program defaults and even exporting/importing reg items. Still no fix. the computer has outlook 2003 but this issue started yesterday and so may have somehting to do with the firefox 3.5.2 update.

    Thank you soooo much. Just like some of you who finally came across this site, I was having problems with my email hyperlinks. Tried to follow a few suggestions on other sites, but this hit the jackpot. My Outlook is back to its normal self again. Thanks!

    The problem with me started after I installed Google Chrome. The control panel method shown solved the problem. (I have three browsers installed, Chrome, Firefox, and IE. The addition of Chrome probably confused things.)
