Questions regarding E-mail message lifetime
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:
- When I enable it, will it instantly start scouring mailboxes to delete old messages?
- 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!
