You can access your email from any location and on any computer through Outlook’s Webmail interface via web browser. You will be able to send email, edit your calendar appointments, access your tasks list, and even set an Out of Office message.
NOTE: Your signature will not carry over from your computer’s Outlook to Outlook Webmail – but you can re-create your signature in Outlook Webmail through the Options menu. Just look for one of your Sent messages for the existing signature.
Step 1: Type https://outlook.office.com into the browser address bar (or click the link to open)
Step 2: It will take you to the login screen. Enter the same username and password you would use to log in to your computer. Click Sign In.
