I need to add resource delegates to exchange 2007 resource rooms.  I know the PS command to do that and I have a list of rooms and delegates to which I want to add, but I don't know how to put that in a csv file (or any other type) to call a batch and automate.

Well, I don't know squat about Exchange 2007, but ...
If you put the room and delegate in a csv file like (for instance):

RoomName, DelegateName
room1, delegate1
room2, delegate4
room3, delegate18

you can just import it using the Import-CSV cmdlet:

Import-Csv .\test.csv

and then you could use ForEach-Object, and access the RoomName and DelegateName properties ... bear with me while I make a cmdlet up:


Import-Csv .\test.csv | ForEach-Object { Whatever-COmmand -Room $_.RoomName -Delegate $_.DelegateName }
