After 8.1 I am unable to get push email on my Exchange work email (selecting 'as items arrive'). Before I was able to add my work email under Outlook.com part of the email+accounts settings. Now it appears we need to use Exchange when adding a new account. The server finds my settings correctly, but I can't get push email, options now are every 15/30 min, etc. Did they remove this intentionally for 8.1? Trying to go through adding a workplace account fails outright, being unable to find settings (but that never worked on 8.0 either).
Another note, on 8.0 when I added my work email it was able to detect Lync 2010 being available, and now it did not.
