smtplib/exchangelib connection to the email server error

Question

I used to use auto discover to retrieve some emails from my inbox using exchangelib. However, last week they updated my email and auto discover is not working anymore. Now I am testing the connection with SMTPLIB using SMTP_SSL

server  = smtplib.SMTP_SSL('xxxxxxxx.com',port=25) 

but I get

When I used auto discover on exchangelib I got

I don't know how to deal with these exceptions
