1. how send html data within same email?
   
2. also outlook .ics file not getting download
   appreciable

you should not add custom headers - break things.

phpmailer includes simple ics generation class called easypeasyics. it's simple, important things. how use it, refer this example in test suite.

however you're generating it, stick ics data $mail->ical , added multipart/alternative text/calendar part alongside usual text/html , text/plain parts. tricky , unreliable in clients, , run trouble if try use attachments @ same time.

unfortunately phpmailer doesn't let build arbitrary mime structures, , messy support ical parts more comprehensively, in face of broken support in clients require messy workaround, this issue discusses.
