On an iPad 2 running 6.0.1 (10A523). Flagging works for gmail and me.com accounts. None of which are setup as exchange accounts. Setup work exchange account, using the add account, exchange, method. I have tried with and without domain. I have changed push/pull, number of days to sync, number of messages to review. The exchange account is the primary account for mail, contacts, and calendar. Activesync. Yet I do not have the ability to Flag email in the exchange account. My fellow colleagues can on their iPads, and iPhones. Same mail setup and settings, and software versions. Tried it on my wife's 4s, same result. This is a huge hang up for me, as I have to migrate from BB to either IOS or Win 8. Any suggestions out there?
