Once you open a message, you can read it, reply to it or forward it to someone else.
Open your e-mail software program.
Open the Inbox, which contains the e-mail messages that you have received.
Locate the message you want to open - new messages will typically be highlighted - and select it by clicking on it.
Double-click to open the message.
If your e-mail software has a Preview function, you can read messages before opening them. Though some programs do this automatically, you might need to click a button or find a Receive or Send and Receive menu command to access an e-mail account from your ISP.
E-mail attachments can contain viruses. It's wise to run a virus scan before opening attachments.
