Microsoft has made the Exchange 2007 SP1 help file available for download at download center. It is a chm file of 20MB size which covers the following topics..
o Planning and Architecture (includes AD planning and E2K7 roles planning)
o Deployment (covers fresh installations and migrations)
o Operations(covers various administration tasks)
o Very useful troubleshooting tips
o Configuring security and protection in Exchange 2007
o Technical Reference for administrators like me who loves to read some internal stuff. 🙂
o PowerShell commands
I downloaded this and had glimpse at it. I felt that is useful for every one. Hence I wrote this post.
