A user complains that a calendar invite to three employees was not responded to, and those employees state the invite was never received. The calendar invite is for 10/2/09 and clearly shows the thre employees in the To field. A check of our e-mail archives does not show this message as being sent, but the calendar invite clearly looks like the invite was sent. The meeting does not appear in the three employees' calendar, but it does in the sender's. The invite also states - no responses have been receivd for this meeting. There are three attachments to the meeting, and it may have been sent from Outlook or through the user's Blackberry, which is connected via BES, and has no other e-mail accounts setup. Any suggestions? This has happened to me once, when updating a calendar invite on my Blackbrery. The recipient never received the update. I am also on BES.
