I started focusing more on Active directory. I thought it would help others to share my experience not just related to Exchange, but also Active directory, powershell scripts and so on.
Having said that, I was tasked to extract the information about my active directory topology,
Microsoft Active Directory Topology Diagrammer, tool was very useful.
But that wasn’t sufficient to document. I have found a script which extract almost all the information about your forest.AD Discovery script
There are 3 scripts, you can use either GUI or .exe file. I have ran this in my environment several time without any issues
Note: I don’t own this script. I’m not responsible for any consequences caused by this script as i didn’t program it
