Hello Angus
Many thanks for your tips.
I found problem where on the configuration of SslContext.
I don't remember when I set SslVersionMethod to "SslV23", I changed it
to "SslBestVer" and the problem has disappeared.
Many thanks to all
Xavi

Recently a client has migrated all email accounts to send mail
using office365 server.
Now my programs can't send email using that server. Always get
"Error=535 5.7.3 Authentication unsuccessful"
I tried many options but always get error 553.
The limited information in the log appears to show the server connects
correctly with SSL, with authentication fails, which is most likely a
bad login or password. The AUTH command has worked for many years,
unlikely to be a problem with it.
Exactly which version of ICS are you using? Anything related to SSL
really needs the latest versions of everything since it changes so
often.
ICS will send email using Microsoft hotmail.com, live.com, outlook.com,
although this appears to be more modern server than office365.com since
it also supports XOAUTH2 (which we don't).
