The other day I was chatting with one of our Supportability Program Managers, Nino Bilic, and he mentioned something that was rather alarming  - the number one reason why our Premier customers open Exchange 2010 critical situations is because Mailbox databases dismount due to running out of disk space on the transaction log LUN. 

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!).
