Same problem happened to me yesterday when trying to set up my wife's email on her Android phone [using Outlook].
Just keeps coming back saying username or password is wrong [which it isn't] but she can still login to her account on webmail on our desktop computer.
Tried accessing her account using chrome on the phone but wouldn't accept username/password on that either [same username and password that is accepted using chrome on the desktop !]
Any ideas or do I just have to keep trying till BT get round to fixing it?
Solved! Go to Solution.
If she can log on via a web browser on your PC but she can not log on via a web browser, Chrome, on her phone it would appear that the problem is not with the IMAP servers.
When you tried Chrome on the phone were you using a wireless connection or the 3g/4g phone connection?
When you log on via your computer are you entering the user name and password or is it stored on the computer?
Are you using the BT log on page.
Was using a wireless connection on phone
Logging on via computer, username and password is stored in vault on computer.
When setting up the phone, are you 100% sure that you are using the same log on and password that is stored on your computer. Are you able to view the stored details to confirm it is the same as you are entering on the phone?
Have you tried turning off wireless on the phone and seeing if you can log on via Chrome on 3g/4g?
