Exchange 2007 running on SBS 2008. Log files are 35gig and I want rid of them so that I can configure circular logging. I do not want to go to the botther of installing an exchange aware backup program if I can avoid it. Having said that if that is the only safe way of clearing them then I will do it. Can I just enable circular logging and that will clear them automatically and safely. I am aware that circular logging wasnt recommended up till Microsoft changed their minds with 2010 which has it enabled by default.
