On other calendar tools, it is possible to anwer with insertion of a comment: it is usefull when you reject a meeting to give a reason to requester.
Hi R1M,
Thank you for your suggestion. It’s true that we don’t have this feature which for example Outlook has and so I added it to our feature request list.
