I am also having this problem. I have found 4 solutions online, all of which have not worked. I am running Windows Vista 32 with SP2 Beta, Outlook 2007, and Internet Explorer 8. Here is what I have tried.
1. Restoring Internet Explorer defaults through Internet Options and making sure Internet Explorer has all defaults through Default Programs.
2. Importing the registry entry from another computer as described in the link above (also referenced in Microsoft KB).
3. Reregistering services through Run... , regsvr32 Shdocvw.dll, urlmon.dll, Mshtml.dll, Shell32.dll, Actxprxy.dll, Oleaut32.dll
a)all of these are successful except Shdocvw.dll and Mshtml.dll which give me the following error:
"The Module "Shdocvw.dll" was loaded but the entry-point DllRegisterServer was not found.
Make sure that "Shdocvw.dll" is a valid DLL or OCX file and then try again."
b)Shdocvw.dll and Mshtml.dll are valid DLL files in the folder SYSTEM32
4. Making sure that file associations for "URL:HyperText Transfer Protocol" is associated with Internet Explorer 8.
Any further help would be greatly appreciated, as the copying and pasting of links from email only works 90% of the time.
I am at my wits end with this. Whenever I click on a hyperlink in Outlook 2007 I get the following message: "This operation has been canceled due to restrictions in effect on your computer. Please contact your system administrator." I am my own administrator, my account time is administrator and I cannot find the setting to allow me to open hyperlinks. Even when I click on email addresses on the To: line of received emails, it gives me this message. No hyperlink of any type will open. This is not affecting IE alone. I have Norton (Symantec)as my antivirus. I have looked at the Trust Center and that did nothing for me. Where is that change? I am getting frustrated!!!!
