iOS 26.2 BT Mail not leaving outbox

The_Broons — Wed, 28 Jan 2026 09:35:14 GMT

Since apple updated their OS to 26.2 BT mail hangs up in the outbox and you are prompted for the account password, which is not recognised. All other folders synchronise normally, including "drafts". This occurs on apple mobile devices and on MacBooks alike.

Apple says it is not caused by their software, so does anybody in the BT Community have a solution?

PS: BT Webmail works as normal and passwords/IMAP details are correct.

So, your mail works ok until Apple do an upgrade whence it stops working, but Apple say its not them causing the problem!!!

I suspect Apple have somehow made changes to the SMTP configuration, possibly encrypting the password which is not required as the whole connection is encrypted.

Thanks Liquorice,

But I'm not trying to blame anybody, I just want my mail to consistently send when I press send. All other synchronisations work absolutely fine, except the send one.

If you could shed a light on a fix that would be good.

You are probably better asking on an Apple forum as they appear to have broken things.

I don't use Apple devices so can't give a detailed description of how to check, but ensure your SMTP configuration is Port 465, SSL and plain password.

I am assuming you are BT broadband customer or paying for Premium Mail. If neither your email will have been downgraded to Basic Mail which cannot be used with a mail client.
