Accept/ Decline/ Tentative outlook meeting request via excel sheet

Hello experts,

I have a macro which downloads all calender invites information in excel sheet.

Now considering any one request how do i Accept/ Decline/ Tentative the status via excel sheet?

Any way out.. any advise.. anything which will help achieve this..

Customer do not want to touch outlook to do this.. rather controlling it via excel is allowed...


Plz suggest.. thank you...
