Several clients have recently asked about BES support with Domino 8. Official support for R8 will come in 4.1.5. We had initially been told by RIM that this should be available before December 2007, however there is a lot of web chatter indicating that this may have been delayed until Q12008. BES 4.1.4 can "work" provided you can live without certian functions. See the official RIM technote for further information.
