To change the default e-mail program

A common issue with Microsoft Internet Explorer is controlling the e-mail program used when you click on a mail address on a web page. If it's not set correctly, you may get a "Can't create object" error message.

Changing the default program

The easiest way to set the program is to use the Internet applet in Control Panel or choose View | Internet Options in MSIE. On the Programs tab, select the program you want to use from the Mail list.

If you don't see a change, even after restarting MSIE or restarting Windows, then you can make this change manually. In Windows Explorer, choose View | Options. On the File Types tab, you'll need to edit the Open event for "URL:MailTo Protocol." Sample entries are as follows, for different Microsoft e-mail programs:

Internet Mail and News rundll32.exe C:\Windows\System\Mailnews.dll,Mail_RunDLL
Outlook Express "C:\Program Files\Outlook Express\Msimn.exe" /mailurl:%1
Windows Messaging or
Microsoft Exchange
rundll32.exe url.dll,MailToProtocolHandler "%1"
Microsoft Outlook "C:\Program Files\Microsoft Office\Office\Outlook.exe" -c IPM.Note /m "%1"

Adjust the path to Mailnews.dll or Outlook.exe as needed to match your own system.

To get mailto links from Netscape to use Outlook or Exchange, the free NSOutlook program makes the necessary changes for you.
