I have migrated the mailboxes from SBS 2011 exchange to office 365 so everything is hosted.
I face issues with the outlook trying to connect to the local exchange.
to get through that I change the local DNS on the machine to public ones .
But I need to get in back to the local DNS so it can access the server as file server.
What is the best way to solve it
disable all exchange services? disable the mailboxes ?
or other ways?
