Finding the Server Name
To determine your server name, use the following steps:
1. Sign in to your account using Outlook Web App.
the Outlook Web App toolbar, click Help > About.
the About page, under the External POP Settings
line, use the Server name value to help you determine your
If the External POP Settings > Server name value
includes your organization’s name, for example, pop.contoso.com,
then your server name is the same as your Outlook Web App server
name, without the /owa. For example, if the address you use to
access Outlook Web App is https://mail.contoso.com/owa, your
Exchange ActiveSync server name is mail.contoso.com.
If the External POP Settings > Server name value is
in the format podxxxxx.outlook.com, your Exchange ActiveSync
server name is m.outlook.com. In some cases, Android
mobile devices may experience connection problems using
m.outlook.com as the server name. If you are having problems
connecting, go to the Host name line on the About
page. Use the value shown under Host name for the Exchange
ActiveSync server name for your device.

phone. For more information about how to sign in to your
account using Outlook Web App, see

signing in, see
FAQs: Sign-in and Password Issues or contact the person
who manages your e-mail account.
When you use the Host name as the Exchange server name
in your e-mail account settings, you should be aware that
