•If you changed your password in an online email account, you must change the password on your device (see Change account login settings).
•Make sure your email provider or ISP allows you to access email on a device via POP or IMAP. (Some providers do not offer this option at all; other providers require an upgrade for you to access email on a device.)
•Email provider settings may change. If your email account was working but you are currently experiencing problems, check with your email provider to find out whether any of the account settings have changed. You may need to manually change some email settings on your device (see Enter advanced account settings).

I have problems sending email (IMAP and POP accounts)
If you are able to receive email messages but cannot send them, try the following:
•Turn on authentication (see Set up email when automatic setup fails). Many service providers require authenticated access, or ESMTP, to use their SMTP servers for outgoing mail.
•Confirm the port number for the outgoing mail server. Many ISPs require a specific port number, and that number may differ from the default port number.
•Enter the name of a different outgoing mail server for sending mail (see Set up email when automatic setup fails). Many ISPs, such as cable companies, require that you have an Internet connection to their network to send email through their servers. In this case, you can almost always receive email from these accounts, but if you want to send email, you must send it through another server. Check with your email service provider for the correct outgoing mail server name.
I can send but not receive email (IMAP accounts)
Some IMAP email providers don’t support the setting to receive email As items arrive. Check with your email provider to see if this situation applies to your account. If your device is set to receive email as it arrives, try changing the Sync setting for Get Email to 5 or 10 minutes (see Enter advanced account settings).
After I receive messages, older messages disappear from my Inbox
When email sync takes place, by default, the last three days’ worth of email messages is downloaded from your mail server to your Inbox. All messages older than three days are removed from your Inbox; they are not deleted on the server, however.
You can change the setting to download only one or two days’ worth of messages. If you select one of these options, any messages older than one or two days are deleted from your Inbox. You can also change the setting to download all messages regardless of the date, in which case all messages continue to appear in your Inbox (see Enter advanced account settings).
I have trouble sending or receiving attachments
•Email attachments smaller than 150KB are downloaded automatically. All other attachments have to be downloaded manually by tapping the attachment name in the email. You may need to tap the attachment to complete receiving it.
