We have an old program which i believe is built using C# for which i have the source code but i cannot edit the program. The issue is we have moved our email to a new provider who is using STARTTLS for sending emails and our program is now failing to send a simple email and returning the error below;
sendemail - Error in processing. The server response was: 5.7.3 STARTTLS is required to send mail [LO4P123CA0676.GBRP123.PROD.OUTLOOK.COM]
We have an XML file which we can change the values of but i cannot see anywhere to add anything to allow the STARTTLS to work.
Specify STARTTLS credentials in XML file which is called by a C# program
in XML
