Cannot Send Mail - the username or password incorrect - help please?

My Yahoo mail account on my iphone which has been working for a year today stopped letting me reply to emails. I can recieve fine but it will not let me reply to messages, comes up with "wrong username and password". I checked in Settings and they are both correct. I have also done the following but to no avaial:

Changed my password to something shorter with just letters
Turned phone on and off
Deleted the account and setup again

If anyone could help I would be most grateful as I have run out of ideas

3GS, iPhone OS 3.1.3, Yahoo mail account

I do know that yesterday when it wouldn't send outgoing messages on my wife's phone, I added her email account to another Iphone with the updated firmware and it worked fine. After updating her firmware today, it began to work fine. So, if your outgoing mail doesn't start back working, try updating your firmware via itunes.

Yay, mine works now too! I never thought I'd be so glad to hear that "wooooshhhh" sound again. Thanks everyone who called and emailed. I'm sure it got them working on it quicker.

YOu can call ATT at 800 331 0500, option 6, option 3 and then asked to be transferred to the Data Support dept. They will tell you that there is a problem with the Yahoo servers but they wont acknowledge it as an outage until Yahoo confirms it which they havent so far. Who knows why. a workaround is to setup your account using the "other" option. All the fields appear to populate automatically. be sure the "other outgoing server" , AT&T Smtp server is turned on. if you have to add it. the host name is cwmx.com. serverport 25.
You lose folder capability but at least you can send mail until they fix it.
it takes a minute or two for the mail to actually go thru.

I don't know if anyone has said this or not but this us what worked for me. If you go to settings, then mail,contacts, calendars, then select your mail account, then the outgoing mail server (whatever it may be, ex. smtp.live.com), then select the primary server, re-enter your passowrd and it should verify it, then go and try to send an email this worked for me.

I have had similar problems: I have two TalkTalk pop email accounts, 1 gmail and 1 hotmail on my phone. The problem seems to occur for the TalkTalk accounts that I have noticed so far.

I have found that in 'Settings | Mail | Account (TalkTalk account) | Outgoing Mail Server SMTP', that the Primary Server is getting switched off for some unknown reason so the TalkTalk accounts try to incorrectly use the Secondary Servers (smtp.gmail.com or smtp.live.com). Setting the Primary Server (in my case smtp.tiscali.co.uk) back to 'On' solves the problem and mail traffic restarts immediately.

I am having that same problem with my email accounts on my iphone 3GS. I have two hotmail accounts, one personal and one bussiness. Cannot send an emai lfrom either one of them since yesterday. Have re-entered the password for both accounts and checked the user name. Anyone have any information regarding this problem? On the plus side at least I am not the only one with this problem

Hi...

I've had exactly the same issue with my iPhone 4 but only on 1 of my 2 Hotmail accounts, and totally out of nowhere. I'd not changed any settings, passwords or authentication - it just decided to stop sending emails but still allowing me to recieve them.

I did the following and it worked straight away - clearing my outbox...

Settings > Mail > select affected email account > Outgoing Mail Server > Primary Server > (I selected smpt.live.com > enter email account password (this was showing 'Optional' in this box) > Return/Done > password was checked/authenticated and emails started sending.

I would just make sure you delete any emails in your outbox that you don't want sending before you do this.

Hope this sorts it for you & good luck!

This looks like an old problem, but it just happened to me the same way as described above...all of a sudden can't send emails because of an 'incorrect' password on both my Mac and iPhone 4S. I even opened a new gmail account thinking it was my email host (before I saw this chain), and now the gmail is saying the password is incorrect and I just set it up today! Help!

I have tried the fixes in this chain with no results...

Thanks,

Jennifer

Can someone let me know what you mean by setting the account up under 'other'? I am having the same problem, even after getting a new email address. Help!
