The support article (Add email accounts) doesn't mention ActiveSync. If you tap "Manual setup" what options do you get there?

Note: I read on a discussion on the web somewhere that Firefox OS does not yet support some of the security policies that usually are required by Exchange. I searched briefly in Bugzilla, but didn't find a relevant bug for that so I'm not sure of the status.

I had already pushed "Manual setup" and configure all options but doesn't work. I think, may be a problem with SSL protocol.
