I'm unable to send email from my iPad when I'm on wifi. The error message says the connection to the outgoing (server server name)failed. I have to first activate cellular data, which I sometimes don't want to do, then deactivate cell data when I'm finished.
What must I do so I can send email when on wifi?
Are you, by any chance, using a POP mail account AND are not at your home when trying to send the e-mail? For a POP mail account, your mail goes through the ISP server. If the server sees that you are not sending from your home, it will reject the mail packet. It's an authentication and security "feature" for the ISP.
Time Warner/Roadrunner does this - you canNOT send e-mails from the Time Warner account if your not on your home server. And, Time Warner only has POP mail; it cannot be changed to IMAP or Exchange. You can receive e-mail fine - just can't send it while away from home.
I work around this by using a Gmail account as my default (it's my "send from" address). So, I can send from anywhere via WiFi. Yeah, it's annoying (not to mention having different reply e-mails), but its the only workaround. However, once the IMAP/Exchange account is set as your default, you don't have to worry about it again.
Just a thought. If you don't have a POP email account ... never mind and, I don't know why you can't send mail. Sorry.
