Now I have this code:
mailto:{0}?subject={1}&body={2}
This open my default mail program (in my company outlook) and write {0} in To: {1} in subjet and {2} in body.
But now some people in company starts to work with OWA of office365
I can't continue using mailto: because I can't configure OWA like a programn in windows.
I try with this ways.
Link with parameters
https://outlook.office.com/?path=/mail/action/compose&to={0}&subject={1}&body={0}
This seems to work but after one second the webpage make redirect and I lost my e-mail.
Link direct to new e-mail
https://outlook.office365.com/owa/#viewmodel=IMailComposeViewModelFactory
But this open a new e-mail but I don't know how to send parameters.
