@Tom McCoy You need to undelete 400000 files under single container or different containers?

Hello @Tom McCoy ,
I just tried to undelete 10,000 blobs under the single container using below powershell script.
Script took 8 Mins : 15 seconds with out any timeouts and failures.

Kindly let us know if it helps!

////////////////////script//////////////////////////////

$StorageAccountKey = "key"
$StorageAccountName = "accountname"
$StorageContainerName="containername"

$ctx = New-AzureStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey
 
$MaxReturn = 3
$Token = $Null
  $StartDate=(GET-DATE)
do
{
    $blob = Get-AzureStorageBlob -Container $StorageContainerName -Context $ctx -IncludeDeleted -MaxCount $MaxReturn  -ContinuationToken $Token
    if($blob.Length -le 0) { Break;}
    #Undelete the blobs
    foreach ($b in $blob)
    {
        if ($b.IsDeleted)
        {
           $b.ICloudBlob.Undelete()
            echo "Undelete Blob: $($b.Name)"        
        }
    }
 
    $Token = $blob[$blob.Count -1].ContinuationToken;
}
While ($Token -ne $Null) 
$EndDate=(GET-DATE)
$minutes = (NEW-TIMESPAN -Start $StartDate -End $EndDate).Minutes
$seconds = (NEW-TIMESPAN -Start $StartDate -End $EndDate).seconds

Hello @Tom McCoy ,
Manually you can select all the deleted blobs and click on 'undelete' option ?
Or you can use a powershell script
