Although you can delete a meeting request directly from your Inbox, you should properly process the meeting request by either accepting or declining it.
Events are changed the same way as appointments or meetings, unless you have an all-day event such as a conference.
By default, all-day events are defined as midnight to midnight.
If existing attendees need to know that an additional attendee was added to the meeting, then the organizer must open the meeting and send a meeting update to all of the attendees.
Note: If you want to let someone know about a meeting, but not invite them, simply drag the meeting request from your calendar to the Mail icon on the lower left side of Outlook.
• Meeting request is out of date• Outlook Calendaring Issue : Meeting "Not Current", unable to accept meetingupdates.• Recurring Meeting "Not Current," unable to accept meeting requests• "This meeting request was updated after this message was sent" There are some indications this may be caused by a difference in clock times between the Outlook client, and the Exchange server.
