    }

    if (CountValue <= 7)

    if (CountValue <= 30)

    catch (Exception ex)
    {
    Response.ErrorMessage = ex.Message;
    }
    finally
    {
    runspace.Dispose();
    }
    //return Response;
    return Response;
}

I want to connect to exchange and return the recent users from past 7 and 30 days.

I've developed a powershell script that I run to do this. You can also change the WhenCreated attribute to another date attribute if needed. I usually run the commands to remote in separately with these commands

$cred = Get-Credential
(enter full email address and password)
$Session = New-PSSession -ConfigurationName Microsoft.Exchange 
  -ConnectionUri https://ps.outlook.com/powershell/ 
  -Credential $cred -Authentication Basic -AllowRedirection
Import-PSSession $Session

But you could put them in your script if you want. I usually run this script manually. You just need to change the number of days (make sure it stays negative), put in the correct file path and add any other attributes you want to get.

$fpath = "c:\users\(currentuser)\desktop\UserCreateDates.csv"
$numdays = -30

$logfilePath = (Test-Path $fpath)
if (($logFilePath) -ne "True")
{
    New-Item $fpath -ItemType File
    Add-Content $fpath "Name,EmailAddress,Created"
}
else
{
    Clear-Content $fpath
    Add-Content $fpath "Name,EmailAddress,Created"
}

$date1 = [DateTime]::Today.AddDays($numdays)
$Mailboxes = Get-Mailbox -ResultSize Unlimited -filter {RecipientType -eq "UserMailbox"} 

ForEach ($Mailbox In $Mailboxes) {
$DisplayName = """" + $Mailbox.DisplayName + """"
$UPN = """" + $Mailbox.UserPrincipalName + """"
$mailboxCreated = $Mailbox.WhenCreated
if ($mailboxCreated -gt $date1)
    {
        $DisplayName + "," + $UPN + ",""" + 
        $mailboxCreated + """" | Out-File -FilePath $fpath -Append
    }
}
