XFOR: Meeting Request Non-Delivery Report When Sent to Multiple Recipients

If you create a meeting request from a Microsoft Outlook client and you select multiple Lotus Notes recipients or a distribution list (DL) that contains multiple Notes recipients, you may receive a non-delivery report (NDR). The description of that NDR contains the following string: In the Microsoft Windows NT application event log or the Log Browser (visible through the Exchange Connectivity Administrator utility), the following is displayed:

This problem can occur because the meeting request has been split into multiple messages. These messages are then placed in the Mail.box file on the Notes server. The first message is placed properly, but subsequent messages may not be placed properly because the messages are all given the same document ID (because the messages are sourced from the same meeting request). Notes only allows unique document IDs in the Mail.box file at any point in time.

To work around this problem, make sure that the manner in which the distribution list is expanded is correct. Ensure that the Notes custom recipients all reside on the same Exchange Server computer, or that the distribution list is expanded by only one Exchange Server computer.

This problem can also occur if you send a message to a distribution list that contains Exchange Server mailboxes with Notes custom recipients listed as alternate recipients.
