The change to the new ESU 9 web site has created some more specific requirements in configuring and checking esu9.org e-mail accounts. The web-based mail system is now located only at https://mail.esu9.org/webmail. Additionally, if you had configured a client or mobile device to check and send e-mail through the server, the server name must now be specifically mail.esu9.org as opposed to esu9.org or other names you may have previously used.
Additionally, the esu9.org e-mail server will have significant maintenance in the summer of 2017. We are strongly recommending that you forward your esu9.org address to another account. More details will be available as the migration and maintenance gets closer.
