# Webmail Access (Outlook Web App)
Webmail is your online copy of your mailbox which you can access via a web browser. Useful if you're travelling, or you don't have your mail setup on a mobile device. The webmail provided with Exchange is known as Outlook Web App.
We will normally set up your domain to link to the Outlook Web App using a sub-domain. For example, http://owa.your-domain-name.com.
