SMTP with office 365

I’m trying to configure a new email server with office 365 and I’m having problems by sending emails I can receive with no problems.
I’ve enabled bedug=true but I’m not seeing the messages between email server and SMTP.
On the other hand If I look at the strategy I’m seeing that is not being send and is returning a no description error.

questions are :
is the any reason why I’m not seeing smtp messages between smtp and email server?
is anyone using email server with office 365?

[smtp-client]
cnx-check-idle-time=00:00:30
cnx-max-idle-time=00:05:00
cnx-pool-size=10
connect-timeout=00:05:00
enable-authentication=TRUE
enable-debug=TRUE
password=8012164BBBE3CCFCDB777909DB095B74
port=587
protocol-timeout=00:05:00
server=smtp.office365.com
smtp-connection-security=start-tls
user=[email removed]

I can provide any other details that you may require

I guess is
true and not TRUE

Also is 587 secured? If so you won’t see the message exchange.
Run a sniffer and check

yes the TRUE is in upper case I just typed here by hand.
do you know another this that I’m missing that for some reason could be the one that prevent us to send email through office 365?

Logs mister
Maybe firewall? Can you send manually by telnet
