Archiving Rules verification

That's entirely up to how you setup the rules, but maybe I'm just not understanding your question.

From a logic flow standpoint, the first thing that happens is the Archive Task logs on to the mailbox and reads the policy and also what message classes it is meant to be archiving.

 

It then trawls the entire mailbox, examining each and every single message determining whether its inactivity period has been met (the 'all items older than x days/weeks/months etc)

 

Then it creates a sort order, and if the option is checked it will start with large items, regardless of date, so as long as its not younger than the 'never archive items younger than....' period

 

So it should go something like

 

-> Read message classes and policy

-> Examine each message, size and date

-> Remove items that are too young

-> Sort items in to largest to smallest (if the option is checked)

-> Sort items from oldest to youngest

-> archive each item

 

This is obviously for Date based archiving, similar rules apply for quota

Thanks for all your help guys..
