We don’t have as many users as you (600) but on the assumption that Legal/Chiefs give you some kind of clue as to what they’re looking for – content, attachments, dates, recipients/senders etc etc then it works fine. Without search parameters you’re dead in the water, hold your ground and get good background info before wasting days searching for the wrong stuff.

Content searching in DA is painfully slow as there’s no Index, but most other things work OK – plus there’s pretty good result handling (copy/move to file/pst, or delete, using original folder structures or not) and good documentation (OK, you have to create CSVs and do some work from there, but everything is there for you).

Or you might want to look at ISYS – I’ve not used it but have done some research into alternatives, it creates an Index so should be quick – a bit more expensive than DA but still on the cheap side.

Hope this helps

Cheers
