Hi,
For some reasons, it still doesn't work. I have change the setting (Type de validation) from network to device and got the same error.
I have checked under "connectivity" and under "email" to ensure I have the same settings and I do.
From the console screen, when I'm trying to test the connection, I have username and/or password doesn't match. I have checked the spelling of my username and password more than once and typed again, still doesn't work.
