Export to PST via Powershell

I am continually expanding on my offboarding process within Orchestrator. I decided to add the export of the email so that all that has to be done is go to the Content search and download it (unless ...

    No way to do it without going to the SCC and initializing the download via the click-one app, sorry. Perhaps you can automate it via AzCopy or some other tool that takes container/token as input - you can get those via the Result property of Get-ComplianceSearchAction.

     

    As for the cmdlet, make sure you also use the -Format parameter!

    The Format parameter specifies the format of the search results when you use the Export switch. Valid values are:


    FxStream   Export to PST files. This is the only option that's available when you export search results from the Security & Compliance Center.


    Mime   Export to .eml messsage files. This the default value when you use cmdlets to export the search results.

     

    It's most likely what causes the issue in your case.

I have built out a pretty extensive offboarding script that performs a lot of these tasks. I wonder if there is a way to download from multiple exports simultaneously. I am going to be looking into start-job to see if I can maybe start 4 or 5 downloads at once.

Honestly, I think converting to a Shared Mailbox and avoiding PSTs all together is the best idea. However, in the event you can't, the Outlook Interop seems the best alternative for now...

 

 

 

function Add-PSOutlookStore([string]$StoreFilePath) {
    [void]($comOutlookNS.AddStore($StoreFilePath))
}

function Remove-PSOutlookStore([string]$StoreFilePath) {
    [void]($comOutlookNS.RemoveStore($StoreFilePath))
}

function Export-PSOutlookInbox([string]$EmailAddress, [string]$DestinationFilePath) {
    Add-PSOutlookStore($DestinationFilePath)

    $comOutlookRcpt = $null
    try {
        $comOutlookRcpt = $Script:comOutlookNS.CreateRecipient($EmailAddress)
        [void]($comOutlookRcpt.Resolve())
    }
    catch {
        Write-PSFMessage -Level Critical -Message "Failed to resolve recipient $EmailAddress"
        Write-PSFMessage -Level Verbose -Message $Error[0]
    }

    if ($comOutlookRcpt) {
        for ($i = 0; $i -lt $comOutlookFolderTypes.Length; $i++) {
            $comOutlookFolderType = $comOutlookFolderTypes[$i]
    
            Write-PSFMessage -Level VeryVerbose -Message "Iterating through shared folder type $comOutlookFolderType"
            try {
                $comOutlookRctpFolder = $Script:comOutlookNS.GetSharedDefaultFolder($comOutlookRcpt, $comOutlookFolderType)
                if ($comOutlookRctpFolder.DefaultItemType -eq [Microsoft.Office.Interop.Outlook.OlItemType]::olMailItem) {
                    Write-PSFMessage -Level Host -Message "Successfully copied shared folder"
                }
                else {
                    Write-PSFMessage -Level Verbose -Message "Skipping shared folder as it is non-mail"
                }
            }
            catch {
                Write-PSFMessage -Level Warning -Message "Failed to get shared folder $comOutlookFolderType"
                Write-PSFMessage -Level Verbose -Message $Error[0]
            }
        }
    }

    Remove-PSOutlookStore($DestinationFilePath)
}

 

 

This is just a partial from my PS module.
