Thank you for returning Mr. Clark,
When I do not send the password is presented another error:

Sending: Set status=server.Connect(servername,user,pass,AccessToken)
Error returned: "Erro #6015: Servidor POP3 reportou erro: -ERR Authentication failure: unknown user name or bad password.."

Sending: Sending: Set status=server.Connect(servername,user,AccessToken)
Error returned: "Erro #6015: Servidor POP3 reportou erro: -ERR Protocol error. Connection is closed. 10."

The Token is being obtained through Postman.
I'm using the following Scopo: "offline_access openid User.Read POP.AccessAsUser.All SMTP.Send IMAP.AccessAsUser.All"

I'm sending the following keys in the Postman:

-client_id
-scope
-redirect_url
-grant_type
-client_secret
-code.

Grateful

Claudio Vieira
