Email Client Configuration

We have all current and former students on Cougars Email, which is based on Google's Gmail system, and faculty and staff on Exchange Online.

Current and Former Students (Cougar Email)

All current and former students use Cougar Email by Google. For more information on retrieving your Cougar Email using your own email client, use Google's Documentation at the link below:

Faculty and Staff (Exchange Online)

All Faculty and Staff are on Exchange Online. When you are not at your CSUSM provided computer, you can access email via Exchange Online. To configure a mobile device or access email via a web browser, please visit for details.

Notes on sending email

In order to minimize the amount of spam sent from our servers, we require that all client authenticate with the server before they can send email. And because we require people to authenticate and we have to take their campus passwords over the internet, we require all mail communication to be sent securely via TLS/SSL.

Some clients will figure this out automatically (Mozilla Thunderbird 2, and Apple Mail in OS X Leopard), while some others don't (Apple Mail prior to OS X Leopard, and Microsoft Outlook Express). If your client doesn't figure it out automatically, you'll need to manually enable TLS support. As soon as we get the chance we'll supply screenshots and specific instructions to do so.

Also, some Internet Service Providers (notably Cox High Speed Internet) will block the standard mail sending port (25) in an attempt to stymie spammers. To get around that, we offer our mail sending service on both port 25 and port 10025. So if one port doesn't work for you, give the other a try.
