Re: pmid710x how to send email from outbox
Welcome to Android Central! Which email provider do you use? Open the Email app, tap Menu>Settings, then select your email account. Look for the settings for the Outgoing SMTP server. Compare these with the ones specified by your email provider (to find them, do a Google search for "[your email provider] IMAP POP3 settings").
Another thing you could try is to go to completely remove that email account, then add it back again.
