- You create a meeting that includes a distribution list (DL) as an attendee.
- You later open the meeting and notice that an attendee is listed separately, even though they are also a member of the DL.
- You remove this individual attendee.
If the attendee has a Microsoft Exchange Server 2007 or Exchange Server 2010 mailbox, the Exchange Calendar Attendant processes the meeting cancellation and update automatically. Because the meeting cancellation is received before the meeting update, Outlook marks the cancellation as Not Current or out of date. As an out-of-date item, it is automatically deleted. When the most recent update is processed, the meeting is put in the tentative state in the recipient's calendar. This occurs even if the recipient previously accepted the meeting.
When an attendee is removed from a meeting that contains a DL, Outlook does not display the prompt Send updates only to added or deleted attendees. If Outlook let this occur, the individual attendee would receive only the meeting cancellation. This is not desired behavior and is why Outlook displays only the Save changes and send update prompt.
Meeting responsesBy default, when you create a new meeting, the Request Responses option is enabled. When an attendee accepts or declines your meeting invitation, a meeting response is automatically sent to you. Meeting responses are processed by the Exchange Server or Outlook client. If the attendee is a member of a DL, they are added to the attendee list as an individual attendee. This lets their response be tracked separately.
