My outlook font setting is "Verdana" but when i send email from navision the font is "Calibri"
What kind of email are you sending?
What code are you using?
You can easy set your Font in a email is you are build your email with HTML
Are you handling font name and size from NAV side?
i have used codeunit 397 for email. i have tried code for font style in html but its is not working.
how can i check this
Go and see the NAV code which generated the email including subject and body, there in you will find some html tag where the developer might have used something on font level!
