Just about anything except Microsoft Outlook Express. Due to problems with viruses, we will not support Outlook Express on any faculty or staff computers. If you will wish to check your email from several different computers, we recommend webmail or pine. We also support Netscape Mail, the OS X Mail application, Eudora, mutt, and just about any other email client.
If you would like to switch from Outlook to another email address, you may find useful information about transferring your address book on the following websites:
