How EV finds eligible items, by index or by scanning?

Hello,

 

let's say we have MS Exchange mailbox archiving based on age. Does EV use some "index" on MS Exchange side to quickly find out which items are eligible for archiving? Or it is slowly scanning the mailbox, mail by mail, querying each mail for date?

(in other words, looking for analogy between this and index-based/full table scan based searching in relational database tables)

Interesting question.

We check the properties (modified date or which ever property it is, can't remember off the top of my head) for each message rather than using any kind of Index.

I am checking on this as we speak but this has always been my understanding, if this changes, with what I find, I will update my reply.

There is no special reason like performance problems somewhere. Just interested in archiving processes background.
