Searching for Null dates

[Brad Ott]

I am looking for top-level parents that are missing a sent date. I need to tag them so that I do not export anything of that nature. Importing NSF files and exporting to EML. The end client cannot handle EMLs with missing sent dates. I know I can do this somewhat manualy but I have do this over and over for 500 custodains in different databases. 

Is there an option in the Date column to let me do a search for those items so I can tag them and/or possibly create a task to do this when I load in the NSF?

Hi, I don't think there are any options to sort items with no sent date on ingestion. This will need to be done after indexing by searching on mail types, then sorting by the Sent date column and tagging the items with no dates.
