After installing, Microsoft Outlook starts automatically when you connect to your Internet Service Provider (ISP) and check for mail.


When you installed Outlook, Microsoft Internet Explorer was set to use Microsoft Outlook as your default e-mail client.


In Microsoft Internet Explorer, change the Mail service back to your previous mail client. Installing Outlook modifies the registered file type for the "URL:MailTo Protocol" entry to point to Outlook.

Change the Default Mail Client

To change your default mail client, follow these steps:
  1. Start Internet Explorer.
  2. For Internet Explorer 4.x, on the View menu, click Internet Options.

  3. On the Programs tab, in the Mail or E-mail list, select the program that you want to use as the default mail client, and click OK.
