Whenever I try to click on a link in Outlook (2010 on Win 7), I get told that "Windows can't open this file." I have to select from a list of programs (the web service can't figure it out, either) and force it to use the browser.
This is probably related to Google Chrome. If I set Chrome to be the default browser, the link opens up just fine. If I set it to IE, I get the "Windows can't open this file." I don't want to open in Chrome.
When I go into the registry, there is an entry in HKEY_CLASSES_ROOT under .htm and .html for (Default) that lists Chrome. I have deleted them but that still doesn't work. I have reset them to "htmlfile" from "ChromeHTML," but that still doesn't work though the error changes: It still asks me how I want to open the file, but it seems to know that IE is available and lists it directly as an option. It shouldn't be asking me because I have told it to always use IE.
I have tried to make IE the default program, but it already thinks it is and won't let me change it. I have switched to Chrome as the default and back again, it still doesn't work.
How do I convince the system that these are URLs and they should open in IE without prompting?

It is an issue related to IE. I recommend you follow the article below to check additional two registry entries:

Took a bit of noodling around, but the answer was eventually in there:
Control Panel | Default Programs | Set program access and computer defaults
Set it to Microsoft Windows and save.
Outlook finally behaves.
