This is one of the most common request comes time to time, although there are many ways to accomplish the task I will show you one of the easiest one.
Log into one of your management server ,
Csvde.exe is a Microsoft Windows 2000 command-line utility, so open CMD prompted. Copy and paste below…..
|CSVDE -f GalDump.csv -r objectCategory=person -l "displayName, title, telephoneNumber, department, mail"|
All you need to do it to open the CSV file called GalDump.csv , the fiel will be on the same directory as you ran the command.
If you want everything use this one
