Regardless of whether I accept or decline a meeting request via office365.com or Outlook 2016 on my Mac, the same behavior is present: the original email is sent to Deleted Items. I must then manually move the item back to my "Meeting and Appointments" folder
where I keep that sort of thing.
I maintain the original emails for a number of reasons, and NOT keeping them is not something I'm willing to settle for.
How do I prevent the application from automatically deleting meeting requests after I respond? Please do not reference posts about older applications, because those aren't helpful (I've checked, for instance http://answers.microsoft.com/en-us/office/forum/office_2007-outlook/accepted-outlook-meeting-notices-going-into/ef6616c4-c2b7-42fc-be73-4cd970207636). Hopefully this setting will apply to either application, but if I use Outlook 2016 on my Mac mostly, so that would be my preferred starting point.
