Notes Export Directory shows duplications of Small Meeting Room (4304038)

NME "Notes Export Directory" shows duplicate entries with different SMTP Addresses. See sample below:

Resource | Small Meeting Room | Small Meeting Room/Test_Barsa | small.room@yourdomain.com
Resource | Small Meeting Room | Small Meeting Room/Test_Barsa | Small_Meeting_Room@yourdomain.com

The format for the duplicate name of the objects looks very much like it is auto-generated. This happens when the object doesn't have an SMTP address.

Check the following:

1) Was the SMTP address added AFTER the initial Export Notes directory?
2) Is there a Replication Save Conflict in the NAB that they are hiding?
3) Does a room with a similar name exist in a Secondary, Directory Assistance based, Directory?

In order to remove the duplication, the NME DB will need to be recreated. 

Note: R&D might provide a tool (script) to help the customer removing that duplication.
