cannot send mail message/user name or password is incorrect

Thank you RSKUP...this worked

Under "Outgoing Mail Server" click on "SMTP". Under "Primary Server" it says "smtp.x.com"; click on that and you will find under "Outgoing Mail Server" another password to change (this was still old password). click "Done" will verify and should be good to go.

My password here is not correct, but I am unable to change it..any ideas? Thanks.

It seems like some are going to have this problem. I just had it. I changed my email password on my computer for my email. You therefore have to change it on your I-phone. It took me a while but you need to go to settings and change it in 2 places not just one. I was able to receive email but not send. I received that message about the smpt user name or password being incorrect. Most change there password on the first screen they see, INCOMING MAIL SERVER. BUT you also need to go down to OUTGOING MAIL SERVER and click on your email address beside SMTP,this takes you to a new page where you see PRIMARY SERVER under that you will see smtph.live.com or something like that depending on who you use for email, click on that and it takes you to another page where you will see OUTGOING MAIL SERVER again, there will appear your HOST NAME, USER NAME and PASSWORD......change this password to match your incoming mail password.

Thanks heaps, yours is the one that worked for me. Legend!

After popups stating our username and/or password was not correct, and not being able to receive or send email, we called our email provider and found that the account had been deactivated due to a hacker using our email to send abusive emails to people. Our provider helped us reset the password, and we were good to go. Possible cause: Password too simple!!

Had the same problem just started last week after I changed my AOL password. Entering the new password into iPhone 4S AOL account did not fix anything. Went to the AOL captcha link noted previously and did that. Still no luck on sending mail. Could always receive tho... Could not change password in outgoing mail server on iPhone. Solution was to add NEW server smtp.aol.com, username without @aol.com, new password. Did this for each AOL email account on iPhone (2) then turned off both OLD aol smtp.....and it works fine. Can now send emails.

if you're just having issues with outgoing mail, just re-enter the correct password within the outgoing mail server section and it should verify all.

I ran into this problem this morning on my wife's iphone. We use comast. Had to change the username for the outgoing smtp server to include @comcast.net. Then it started working.

Great, thank you. Could receive emails but couldn't send. Old password was still in outgoing mail server. Changed to new and hey presto can now send mail

Thanks!!! Your advice worked!!!

My Iphone 6 started showing this message out of nowhere as well. the fix was to simply delete the email account and then re-add. Only took 5 minutes and no emails were lost as the phone re-synced as soon as I re-added the account.

That was the best hint, thanks a lot. Suprisingly but Apple support could not work out such an easy case... Really appreciate your hint

Thanks so much. I never would have thought to look there for a second place to enter my password.

Thank you so much you have made my day.

thank you!
