Hi All, 

I have modified the 'My email settings' with a different email address.

I am able to view this email address as 'From Address' in classic for all objects including cases.

In lightning, it is available for contacts (as from address) but am not able to find it for case object .

I want send email from this new email address which is in 'my email settings' using lightning experience. Please let me know if am missing anything or is it an issue with salesforce lightning experience.

Regards,

Senthil Raja A
