Exchange 2007 Imap from Ruby


Has anybody had any luck accessing Microsoft Exchange 2007 Calendar
items. Some time back I was doing some test with Exchange 2000 and
everything went smooth. I could access calendar items, convert them to
iCalendar format but with Exchange 2007 nothing is working. I can’t even
list folder items with

Funny thing is that listing Inbox folder works fine.

I have also tried rexchange approach but it looks like it has problem
listing any folders.

Any suggestion please.
