Sending or receiving an email with an invalid address is treated differently by many online services. Many providers allow you to either suspend or permanently delete your email account. Find the settings for the account and look for a button labeled “account deletion.” Each host has its own unique but easy-to-understand procedure to terminate accounts.
If you attempt to contact the recipient at the above address after canceling your account, it will bounce back.
Go to Tools and select Account Settings. Select File from the upper left corner of the Outlook window. Select Account Settings > Account Settings, then choose your account and hit Remove. A notification informing you that all offline cached material for this account will be erased appears.
