Outlook security error when openning links

When I clicked to open links in my outlook I encountered this error :

“This operation has been canceled due to restrictions in effect on this computer. Please contact your system administrator”.

I searched and most of the solutions were for resetting default programs. Change default programs and reset IE to default . None of them did help me .

I found new solutions here.

The second solution about changing a registry key helped me. but I found the html key not in HKEY_CURRENT_USER but in

HKEY_LOCAL_MACHINE

> Software > Classes

find .htm & .html

in both change the Default String values ( in my case there were Opera.html ) to HTMLFile

save and close and after restarting outlook , links opens fine in IE. 🙂
