I’ll let that sink in for a moment. Naturally I’m shocked…to be completely honest, I thought with the Mailbox Requirements Calculator and our guidance on TechNet, we’d have wiped out this issue by now. After sharing this information with me, Nino decided that I, not he, should write a blog article on the topic of transaction log capacity planning (gee, thanks Nino!).
