AppendText method is not working - winforms

Question

My PowerShell script function:
function Click {
$outputBox = New-Object System.Windows.Forms.TextBox
$outputBox.Location = New-Object System.Drawing.Size(10,150)
$outputBox.Size = New-Object System.Drawing.Size(565,200)
$outputBox.MultiLine = $True
$outputBox.ScrollBars = "Vertical"
$Form.Controls.Add($outputBox)
$userid = $Emailid.text;
$uid=[bool]($userid -as [Net.Mail.MailAddress])
if($uid -eq "True")
{
$outputBox.Text = "Email id exists"
}
else
{
$outputBox.Text = "Email id not exists"
}
$owa = [bool](Get-CasMailbox $userid | fl owaenabled)
if($owa -eq "True")
{
$outputBox.AppendText = " your email id has owa access"
}
else
{
$outputBox.AppendText = "sorry... your email id has not owa access"
}
}
When my button is pressed above function is called, but I am only able to see last result into the $outputBox, but I want both the output in textbox. Also ForegroundColor is not working with it. It gives error, so how to use ForegroundColor with it?

AppendText() is a method. You're using it like a property. Change this:
if($owa -eq "True")
{
$outputBox.AppendText = " your email id has owa access"
}
else
{
$outputBox.AppendText = "sorry... your email id has not owa access"
}
into this:
if($owa -eq "True")
{
$outputBox.AppendText(" your email id has owa access")
}
else
{
$outputBox.AppendText("sorry... your email id has not owa access")
}
As for the foreground color: you don't set that anywhere, and the property is named ForeColor, not ForegroundColor.
$outputBox.ForeColor = 'Red'
