You can save files that are attached to email messages you receive. When you save an attachment, it is downloaded to your computer.
To save an attachment:
From your inbox, select or open an email message that has an attachment.
The email message appears, either in the reading pane or in a new tab. Attachments are listed between the subject line and email body.
Click the attachment you want to download.
From the pop-up menu, click Save.
The file is downloaded according to the way your browser is configured. For example, your browser may be configured to automatically download files to a specific folder, or your browser may be configured to prompt you for a download location and file name.
