Not sure if this is a known issue or not. But we have a user having issues with mailto links in emails in the outlook app.
Typically these links show as hyperlinks in the email. when clicked on, it is supposed to open the 'compose email' popup with the recipient's email address and subject pre-populated. While it works on a variety of other devices(both ios and androids) and other email clients, it seems to be failing on the outlook app on samsung S20+ - on this device, the email popup appears to lose the recipients email address.
