Re: What's wrong with the built-in mail client on WP8.x?
Attachments blow goats on it. Composing a new mail to multiple individuals is a pain. It doesn't pick up Exchange mailing lists well. Flagging is a pain.
Generally speaking, it's not a bad POP3/IMAP client but it's nowhere near the functionality of Outlook Mail.
