Thank you to those of you who appropriately pointed out that if a meeting attendee accepts a meeting but doesn’t send a response, the organizer can’t tell if they are coming or not. This has been discussed in various Microsoft and Outlook blogs. After investigating, we found an alternate option for those of you who don’t want to see routine meeting acceptances. You have two options. You can either 1) set up a rule to automatically send accepted meetings to a specific folder or 2) you can check the box below that automatically deletes the responses that don’t contain comments.
Simply go into Options, and in Mail, check the box indicated in the image.
