Cannot send emails from Android devices

[js1234]

I can receive but not send emails from my Android tablet and phone.  I can send and receive them from my Windows laptop ok. When I first set up email on both Android devices it worked ok but stopped working without me changing any settings. Customer services said it might be due to using an email app (although it used to work) Both devices stopped working at the same time. He suggested some changes in the outgoing settings but then it could not connect to the server so I had to change them back.

I set up the account in the GMail app on my phone, and that seems to work. I can't find any information about what the generic Email app is.
So: for the original poster - have you tried setting up your account in the GMail app?

Oops, just spotted the typo in the server name: it is actuallly smtp.talktalk.net on my phone settings: that's not the problem!

I'm finding the same thing - the settings in my Android email app are exactly what is given in the TalkTalk email settings help document, but my phone won't send email - the message just sits in the Outbox.

Server: smtp.takltalk.net

Port: 578

Security type: STARTTLS (Accept all certificates)

Require Sign-in: checked (then my username and password are set)

The same settings work fine from Thunderbird on my PC...

Your mailbox is less than 3% used. I'd suggest that it's more likely the settings than anything else.

Thanks. The information you directed me to mentioned that my inbox may be full. Could this cause this problem? What is the maximum number of emails which can be stored on the server?

Ok I'd suggest you use the more up to date settings that you can find in the Email Settings Help Article.

I am able to send them using webmail but not the Android email app.

Hi, the email domain is talktalk.net. 

incomingsettings, server: imap.talktalk.net, security: STARTTLS, Port: 143.

Outgoing, SMTP server: smtp.talktalk.net, security: none, port: 587

Hi js1234, what settings are you using? What mail domain is your email address?
