I suspect this is a setting on but I have been unable to find it. I tested sending and accepting invites strictly using 's web interface from my PC and I experience the same problem. The other members of my family experience the same issue when sending their own calendar invites from their WPs. This is a meeting to which I am also invited however this particular invite is received as her delegate. Tentative: You may be able to attend Outlook will. I receive a meeting invite for my supervisor in my mailbox. It would then add the calendar entry to their calendar and I would receive an email notification that they had accepted. Responding to a Meeting Invitation Accept: You can attend Outlook will put the meeting on your calendar. Leaving the meeting request in your Inbox might confuse you later and definitely leaves any delegates (delegate: Someone granted permission to open another persons folders, create items, and respond. They would receive the email, and would select accept from the reply options on their WP. Yes, Outlook allows you to accept or decline a meeting from its time slot on your calendar, but that can leave the meeting request in your Inbox.

What used to happen was I could create a calendar event on my windows phone (my old hotmail is my MS account) and I could add attendees - usually my family members. Several months ago myself and members of my family stopped receiving 'accepted' notifications when we accept each others calendar/meeting invitations. I know this question isn't explicitly WP, but it's definitely related.
