As far as I am aware, you cannot use exchange with a Samba AD DC, so
I think you need to remove all the exchange schema etc from your Samba
AD. I do not know of a way of doing this.

If you still have the windows server, it may be easier to remove
exchange from this and then migrate again.

Don't know if it will work and if you try, try it on a test machine and
don't blame me if it doesn't work ;-)
