For IE7 only:

Control Panel | Add/Remove Programs | Set Program Access and Defaults |
Browser: IE /must/ be chosen here if you're running IE7 and want such links
to work.

Hyperlinks do not work in Outlook Express after you upgrade to Internet
Explorer 7:

If still no joy, for IE6 & IE7:

If nothing happens when you click a link:
Open Windows Explorer, or the Control Panel.
Go to Tools | Folder Options | File Types.
Scroll down to [NONE] URL:HyperText Transfer Protocol (NOT URL:Internet
Shortcut) and select it.
Click Edit or Advanced, depending on your Windows version.
Select 'open'.
Click Edit.

"Application used to perform this action" should read:

"C:\PROGRAM FILES\INTERNET EXPLORER\iexplore.exe" -nohome (Check the path to
iexplore.exe to make sure that is correct and use the double quotes.)

DDE should be checked and in the boxes below it you should have:

#1:
"%1",,-1,0,,,,
#2
IExplore
#3 (blank)

#4
WWW_OpenURL

URL:HyperText Transfer Protocol with Privacy should be the same.

Sometimes it is necessary to uncheck Use DDE.

A friend has OE 6 and when he receives an e-mail with an online link, it
won't open. It has to be copied and pasted into IE (6 also) in order to
view it. Is there some setting that needs to be changed?
