exporting messages from exchange 2007 to a pst file

Make sure you have an exchange admin account, grant it rights on the mailbox you want to export
Add-MailboxPermission -Identity MailBoxToExport -User MyAdminAccount -AccessRights FullAccess

Make sure you have enough disk space to extract the data to
Export-Mailbox -Identity MailBoxToExport -IncludeFolders '\Folder to Export'  -PSTFolderPath C:\Users\jack.oregan\extracted-pst\extracted.pst

get information on a mailbox in exchange 2007

start the exchange powershell console

Get-Mailbox mailboxname | Select-Object name,primarysmtpaddress, DisplayName,Database,@{n="Size(MB)";e = {$MBXstat = Get-MailboxStatistics $_.name; $MBXstat.totalItemsize.value.toMB()}},@{n="Items"; e = {$MBXstat = Get-MailboxStatistics $_.name ; $MBXstat.itemcount}}

how to extract emails from the message queue in exchange 2007

Start the exchange management console
Mark the message as suspended in the queue
Collect the message properties so you have the queue and message ID
Start the exchange management shell

Export-Message -Identity EXCHSRV\5000\10000 -Path "C:\export\exported-email.eml"

5000 is the queue ID
10000 is the message ID

Export the entire queue (I have not tested this)

importing data from a csv file with powershell

This is the contents of my data.csv file:

Col1,Col2,Col3
jack,jack@test.com,1234567
john,john@test.com,7654321

Here is the powershell code of my ImportFromCSV.ps1:

$dataSource=import-csv "data.csv"
foreach($dataRecord in $datasource)
{
    $name=$dataRecord.Col1
    $email=$dataRecord.Col2
    $phone=$dataRecord.Col3
    write-host $name $email $phone
}

Running the code gives the following output:

jack jack@test.com 1234567
john john@test.com 7654321

For this to work data.csv and ImportFromCSV.ps1 should be in the same directory
