Hi all,

I have two questions regarding the "E-mail message lifetime" setting. My college is looking to implement this to set a retention time of 3 years on mail (in the default class of service). My questions about this are:

  1. When I enable it, will it instantly start scouring mailboxes to delete old messages?
  2. Does it cause an initial resource strain on the system (since it would be cleaning up 1500 or so mailboxes)?

I've only found 5.x/6.x era notes on the "E-mail message lifetime" option in the forums (and those somewhat sparse and not specifically about this).

Thanks in advance for any info!
