Sorry, we still have no reliable ETA on ORF 4.1 with Exchange 2007 support as there are too many uncertain points in the development process. We are sorting out technical issues one by one, but with some of these we need assistance from the outside and the lack of official, guaranteed Exchange 2007 development support channels does not particularly help the development. Also, the numerous problems with ORF 4.0 allocated most of our development resources, not allowing us to focus on Exchange 2007 exclusively, but that is changing and I believe we are on the right track now. We are getting closer to version 4.1 and hopefully we can go beta soon.
