Exchange Circular Logging

Hi All,

I have a Exchange 2003 and 2010 (mid migration environemt).

I have not been running backups that commit the logs only snapshots at the LUN level (with a HIT KIT). I wanted to enable circualr logging for a while on DB's on both servers as my log drive is filling up.

do i need to dismount stores or anything before i do this? Will it casue any disruption to user accessing/sending email. When enabling it, will all the logs just be deleted?

Also when i want to renable it, is there a best practice?

Thanks
