Revert to stock Android email app? I've long used the stock Android email app to remotely access my work Exchange email account.

With the latest update of the Gmail app, the Gmail app has taken over this email account, and launching the stock Android email app results in forwarding to the Gmail app.

I'd like to resume using the stock Android email app for this email account.  How can I do that?

Thanks much.
Unfortunately, the only workaround for that would be to uninstall the most recent Gmail app and consider finding the previous update to it (ex, if it was 4.1.3, search Google for 4.1.2.)
