Emails won't send from Hotmail account on iphone as message says password is incorrect
I recently had a problem with my hotmail account which meant it was blocked and I had to go through a securitiy process to unblock my account and change my password. I can now use my hotmail account again and changed the password on my phone settings to be able to use this account on my phone again. However, when I try to send emails from my iphone from my hotmail account, it says my password is incorrect and the emails won't send. I am also not convinced that I am receiving all emails, although some came through when I initially re-added the account. I have tried to delete the account and add it again, as well as restart my iphone, but I am still having the same problem. The password I have for the account is correct! I would be so grateful if anyone could help.
Thanks.
