Powershell script to perform exchange admin tasks

Hi Experts,

I am kind of rush with the export of bulk mailboxes to a PST files and the EAC really sucks to perform bulk email searches and then export the results to multiple PST

Need you help to build a PowerShell script that basically will read from an input CSV file that contains exchange display name, database, and email address

So, for any member on the CSV file

Perform following tasks

' comment, the cmdlet below performs a new search against all sourcemailboxes specified there, but we should use display names for each user within the csv file

New-MailboxSearch -Name "Legal" -SourceMailboxes user1,user2 -TargetMailbox "LegalDiscovery" -StartDate "03/01/2013" -EndDate "07/02/2013" -SearchQuery 'Item1 OR item2'

' perform a search of the entire mailbox to a PST and no search criteria defined
New-MailboxExportRequest -Mailbox User1 -IncludeFolders "#Inbox#" -FilePath \\SERVER01\PSTFileShare\User1\User1.pst

'Once it finished the first search and export for the first user, will perform the remove-mailboxexportrequest to release resources. validate the pst has been created on the shared folder

Get-MailboxExportRequest | Remove-MailboxExportRequest

then repeat the entire process for each user in the CSV file

Can someone please help me with this request?
