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.

I did a quick internet search and found this:

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 ;-)
