Oui, j'ai besoin d'une solution
As we use EV, the default settings for Custodian Assignment in the collection task did not associate a custodian with the resulting documents.
I went back and selected to, 'Create a new custodian using the archive's email adddress' under 'If no match is found:' for each of my 5 collections. and re-ran them for custodian assignment only.
I can now see Custodian Data in the Collections > Analytics chart/table.
Custodian data also appears in the Collection Sets Charts.
Without a clear idea of what else needed to be done, I have tried to re-run post processing and to process without discovery.
I still do not see custodian metadata in the Analysis & Review section however. Any ideas on how to accomplish this?
