how do I stop authenticate box from coming up again and again

[Imray]

Hi

I am having the same problem as many other users in sending email from
multiple accounts and Outlook recognising the fact that I have asked it to
send from a different account in the new message bit.

The fix that was suggested was to ensure that the outgoing server box needs
authentication bit was ticked. I have done all of that and input the correct
details, but keep getting a box coming up asking me to authenticate the
password bit. The details are correct, and the add password to the list bit
is checked but it keeps on coming back and back and won't send or receive
email In the end I have gone back to no authentication and having the
incorrect email address showing at the top.

Any thoughts?
