| Thank you Gianluigi I am using CDOSYS mail component. The checkbox for SSL is by default unchecked.
 
 When I use my gmail SMTP service, the SSL box needs to be checked as it is a requirement of gmail for fort 465.
 
 I cannot get the extension to send messages for smtp.office365.com, the port is 587 and by leaving the SSL not checked, I am not able to send e-mails out.
 Please advise.
 
 Many thanks
