appending content to existing csv file

I have a lot of rooms in our Exchange 2010 setup and I have been asked to produce a list with all rooms and the persons that are ResourceDelegates and are listed in BookinPolicy. I have come this far, but the problem is, that I only have Powershell V2 and -append is a V3 feature.

$rooms = Get-Mailbox -RecipientTypeDetails RoomMailbox

ForEach ($room in $rooms) {

$mRoom = $room.name

$rows = Import-Csv c:\tools\bookingplan\bookingplan.csv

$cont = Get-CalendarProcessing $mRoom | `
		Select Identity, `
		@{Name=’Bookinpolicy’;Expression={[string]::join(";", ($_.BookInPolicy))}}, `
		@{Name=’ResourceDelegates’;Expression={[string]::join(";", ($_.ResourceDelegates))}} | `
			Export-Csv -append -path c:\tools\bookingplan\bookingplan.csv -Encoding Unicode
}

Open in new window

How do I get the output then?

Move the export-csv to outside the for-each loop.

Create a second file and concatenate.

Moving the Export-Csv part outside the foreach loop will only take the last loop.

I have tried to concatenate but I seem to fail on that part. Can you be more specific? Example (please)?

Oops I forgot to declare the array :(
[array]$cont=$null
$rooms = Get-Mailbox -RecipientTypeDetails RoomMailbox
ForEach ($room in $rooms) {
$mRoom = $room.name
$rows = Import-Csv c:\tools\bookingplan\bookingplan.csv
$cont += Get-CalendarProcessing $mRoom | `
		Select Identity, `
		@{Name=’Bookinpolicy’;Expression={[string]::join(";", ($_.BookInPolicy))}}, `
		@{Name=’ResourceDelegates’;Expression={[string]::join(";", ($_.ResourceDelegates))}} 
} $cont | Select * | Export-Csv -path c:\tools\bookingplan\bookingplan.csv -Encoding Unicode

Looking at the script above, you are writing back to the same file you are reading from ?

$rows = Import-Csv c:\tools\bookingplan\bookingplan.csv

Export-Csv -path c:\tools\bookingplan\bookingplan.csv

I might make sense for the moment to just write to another file so you do not lose your source (as you resolve this)  ?

I know this is old, but its exactly what I am looking for. I am having issues running this script. It doesnt seem to create the CSV file before it tries to append to it.
