Does e-mail client software need to be upgraded prior to changing the configuration ?
Most software released over the last few years will work fine. As far as we know all versions of Mozilla Thunderbird, Outlook Express, and Outlook will work. According to Eudora techsupport (http://www.eudora.com/techsupport/kb/2307hq.html) Eudora 5.1 or newer is required. For those using Eudora 6.x.x, version 6.1.1 or newer is required. E-mail software included with the Palm Treo 650 works; we have not tested the Treo 600 or previous models. If there is anyone left using the following old software, these are known not to work: Pegasus Mail, Simeon, ECSmail, Netscape 4.X and older.
