Emails not sending from iphone

[johncollins]

My iphone suddenly stopped sending emails from my BT account, message says my username or password are incorrect.  However I haven't changed password and I am receiving emails and also able to send & receive from my ipad and the web browser.  I have tried deleting the account and reinstalling it on my iphone but getting the same error message.  Any ideas how to fix this?

Are you presently a BT Broadband customer or are you paying for your email through a BT Premium email account?

If neither of the above your email account may have been downgraded to a BTMail Basic account which can not be used with an email client and it will stop on your other devices soon if that is the case.

I do have a BT Premium email account.  Weirdly it has now started working again.  Thanks.

It was probably an email server problem that has been resolved.

If it happens again the best advice is to do nothing especially do not delete the account or change your password as this can cause more problems than it solves.

If it happens again try and access your account via webmail (using a browser). If your account works when you do that it proves there is nothing wrong with your password or account and the issue is not at your end hence the advice to do nothing.  Most server problems are resolved quickly and in any event within a day or two.

I have the same problem, only I had not seen the advice to do nothing and see if it clears on its own. Unfortunately, I have changed passwords and reinstalled my BT mail account - all to no effect. I had my eBay account hacked last week and about the same time my BT mail account started 'playing up', so in a flurry of activity I was changing passwords on everything. Since then it has not worked properly in the iPhone mail app, but it does seem to be ok using the BT mail app. I'm guessing that there is nothing wrong with my BT mail account, and that the issue is with the iPhone mail app. Any help with this would be appreciated.

If the problem did not resolve its self after a day or two or in your instance where you have deleted the email account from your device you should stop your iPhone and any other devices from checking for email. The easiest way of doing that is to turn them off if you still have the account on your device or add a couple of characters to the email address so that it is not checking your account. If you have deleted the account and it is no longer on your device do not try and add it at this time.

Once you have done that, change your email password and check that you can access your email via webmail (on a browser).

If that works you should wait at least an hour to allow the servers to sync and then add the new password to your iPhone, remembering to remove any characters you may have added and again check it works. If it does then move onto the next device if you have one.

When entering the settings, make sure that in the Outgoing server you do not use the "use same as incoming" for the email address and password. Enter them manually.
If the above does not resolve the problem, when you change your BT password on an iPhone/iPad/Apple device it may only change for INCOMING mail.

To change the outgoing mail password you have to go into Settings; then scroll down to Passwords & Accounts or on older devices Mail, Contacts, Calendars. From there select the BT email account and select the account where it is listed under IMAP.

You will find the details for the account and can change the password for the Incoming server there, the outgoing mail server only shows SMTP and mail.btinternet.com You have to tap on that Primary Server in order to find where the Outgoing password is hidden so you can update it.

When setting up the email account on your device you are best to set it up manually, using "other" and ensure that you are using the correct settings as per this link.
