When adding users to your translation table in the CMT for Exchange database, you do not see certain or all users added to the "Add names to translation view" under "Email Repliablity". You try to add the users again and you get a failure and in the status bar the following error appears:
"Error: 82 Notes error: Database already contains a document with this ID (UNID)"
This can happen if all or a certain Domino person document does not contain an internet address for the user.
You will not see the error the first time you add them to the translation table, but because the internet address is not present, the document will not show up in the view. The document is present in the database but is not viewable is this particular view. When you go to add them the second time you will see the failure and the error message in the Notes status bar.
If you then chose "View/Go to/ All" from the Notes client GUI menu and open up the "All" view you will see which documents are in the database under the category "At Person" category.
You can then open the documents and view the contents and you will see there is no internet address present.
Delete the documents from here and correct the internet address field in the Domino person document and try reading the user or users in question
