I have recently set up outlook to access my email account with BTYahoo. I
can receive emails but when I try to send emails I get the error 0x800CCC92
'Your e-mail server rejected your login. Verify your user name and password
in your account properties. Under Tools, Click Email accounts'.

I have disabled my email scanning and also disabled MSMGS (as advised in
previous posts) but still cannot send mail. I even disabled my antivirus
scanner completely but no joy.

The details for logging on are correct and I can access my email account
directly using these details. If I can access my email account directly then
surely this should be working?

I am running Avast anti virus, Windows defender, Spybot resident scanner,
and have a permanant connection to the internet.
