At the moment we have the following effect:
1. Only changes to Recurring Meetings scheduled out of Outlook disappear in Calendars of Lotus Notes users
2. You can find in Lotus Notes users that have this problem [Replication or Save conflicts] in their calendar entry view that point to those meetings or new meeting invitations
3. If the Replication conflict is opened and the meeting is accepted, the calendar of the Lotus Notes user is still not getting updated
Question: What is creating these replication conflicts that make the meetings disappear?
This is being caused by the Notes Client connection model in use.
Presently the Desktop replica is the main mailfile. That is replicated to the Primary Cluster Domino server very frequently. This is turn is replicated to a failover cluster.
When the same meetings scenario was tested and the Primary Domino Server mail file replica was used to see the mail, there were no Replication Save conflicts. The meetings appeared correctly.
There is nothing that CMN is interferring with in this scenario.
