Note 2 email not updating
Email accounts on the i Phone can be set to check email on a defined schedule (every 30 minutes, for instance) or to have mail pushed to your device as soon as it arrives.
How you have these settings configured can impact how your email arrives.
If your email still isn't working, it's time to get some direct tech support for your email problems.
If that's the case, begin by deleting the troublesome email account.
In that case, it's probably best to take your i Phone – and all of the information about the email account – to your nearest Apple Store for tech support (you can also call Apple for support).
Apple Stores are busy places, though, so make sure to make an appointment before heading out to avoid waiting forever for someone to free up.
If you're not seeing Wi-Fi at all and think you should, read Wi-Fi Grayed Out on i Phone? If your email isn't sending or downloading, it could be that there's a problem with the username and/or password you're using to check that email account.
In that situation, it's most likely that you'll get a pop-up window asking you to enter your username or password again.
