    Hi there
    i have a code which compares 3 "states" of a user mailbox size
    initial(from a csv)
    start(quick live run based on list)
    finish(quick run based on list 5 sec after)
    i am running them concurrently using invoke-all to save time using jobs.
    i am not sure i am even using the right approach since the list gets unsorted(i think) which makes the compare not work right
    so i tried using sort but im still not it compares the right data from the same user in all 3 "phases".
    bottom line is i have 3 "lists" of data that i need to compare the same unique user on and see what the differences are and report/store based on that(did the size increase or not...)
    heres the code if anyone has an idea or better way to do it:

    $s=import-csv c:\files\users.csv |Sort-Object displayname -Descending
    $s1=import-csv c:\files\users.csv |Invoke-All {Get-MailboxStatistics -Id $_.displayname} -Force |Sort-Object displayname -Descending
    Start-Sleep 5
    $s2=import-csv c:\files\pilot0sizebefore.csv |Invoke-All {Get-MailboxStatistics -Id $_.displayname} -Force|Sort-Object displayname -Descending
    foreach ($i in $s){
    Write-Host "Working on $($i.displayname)" -ForegroundColor Yellow
    foreach ($j in $s1){
    Write-Host "Working on $($j.displayname)" -ForegroundColor Yellow
    foreach ($n in $s2){
    Write-Host "Working on $($n.displayname)" -ForegroundColor Yellow

    if($1 -eq $2){write-host $($i.displayname) -ForegroundColor red "Restore Started"}
    if ($2 -eq $3){write-host $($i.displayname) -ForegroundColor green "Restore Ended";$Finished+=$i}
    else {$Notfinished+=$i}


    any help would be greatly appreciated

    small update,disregard the invoke-all parts,this can be any command
    the main issue is that bottom line you have 3 arrays with the same users(sorted by name ,looks exactly the same order)
    but the foreach loops take user1 user2 user3 info instead of
    user1(from array1)
    user1(from array2)
    user3(from array3)
    and compares their data
    array1[0] array2[0] array3[0] are the same user data(data itself is diffrent since i took diffrent snapshots of the data)
    that is my main problem:(

    take look at hashtables

    pseudocode example:

    #initialize hashes
    $hash1 = $hash2 = $hash3 = @{}
    #fill table with data (you code here)
    foreach ($user in $users) {
    $data1 = ...
    $data2 = ...
    $data3 = ...
    foreach ($kv in $hash1.GetEnumerator()) # enumerate users in first hash (or may be there should be "($user in $users)" ?
    #get right values from hashes
    $data1 = $kv.Value # or =$hash1[$user]
    $data2 = $hash2[$kv.Key] # or =$hash2[$user]
    $data3 = $hash3[$kv.Key] # or =$hash3[$user]
    #compare data1,data2,data3 here
