[X]: This is a bug and not a question.

[X]: I understand that the best way to resolve this issue is to solve it and propose a Pull Request.

Describe the bug

1. Cannot accept meeting request created by person A on behalf of person B.
   When a reservation is created from person A for person B. Person B will receive an email with ICS file, in which no-reply is not added in email address. And then, outlook mentions that we are already the owner with this message :
   "As you are the organizer of this meeting, there is no need to respond."

2. On reservation deleted, the ics file received does not contain the good METHOD, neither the good STATUS.

To Reproduce

Steps to reproduce the behavior:

1. Create a reservation for another person. Ask this person to accept the meeting. He can't.
2. Delete a reservation, ics received will have the following fields:
   a. METHOD:REQUEST instead of CANCEL
   b. STATUS:CONFIRMED instead of CANCELLED

Expected behavior

1. Can accept the meeting request/edit.
2. Can remove deleted meeting, with METHOD:CANCEL and STATUS:CANCELLED
