As part of my application it generates an auto email in HTML format which contains a MAILTO. The problem it is not allowing to Click the link. If I copy - paste same into notepad and save it as HTML file it works fine without any issues.
In Outlook I have two MAILTO links with almost same and one works and other doesn't. Please find the HTML code
