Just a quick note to let you all know that the Protecting Exchange Server with DPM 2007 white paper is available for download from Microsoft. This is the same white paper I worked on for them last year, but freshly revised to include more guidance around mailbox-level recovery.
I'll be giving a talk around this topic next week at Tech-Ed (IT Pro) in Orlando, session number MGT369. Hope to see you there! (Yes, this is the same talk I did at Exchange Connections in Orlando and in MMS in Vegas a month ago; it seems to be a popular session!)
