Interactive menu to choose task

[coxygt]

Hi,

I have started a new script for a routine task (checking resource meeting settings).  The menu appears fine, but I am now not at all sure how to complete the script.

#Connect to Exchange Online

$MFAExchangeModule = ((Get-ChildItem -Path $($env:LOCALAPPDATA+"\Apps\2.0\") -Filter CreateExoPSSession.ps1 -Recurse ).FullName | Select-Object -Last 1)

. "$MFAExchangeModule"

$un = Read-Host "Enter Username"

Connect-EXOPSSession -UserPrincipalName $un

#Build a menu of choices

Do {

 if($Action -eq "")

 {

  if($Delay -eq $true)

  {

   Start-Sleep -Seconds 2

  }

  $Delay=$true

 Write-Host "********************** Resource Calendar Delegate Booking Settings *********************" -ForegroundColor Yellow

 Write-Host "*                                                                                      *" -foregroundcolor yellow

 Write-Host "*    1.Change delegate booking to Automatic                                            *" -foregroundcolor yellow

 Write-Host "*    2.Change delegate booking to Manual                                               *" -ForegroundColor Yellow

 Write-Host "*    3.Check another resource calendar                                                 *" -ForegroundColor Yellow

 Write-Host "*    4.Quit                                                                            *" -ForegroundColor Yellow

 Write-Host "*                                                                                      *" -foregroundcolor yellow

 Write-Host "****************************************************************************************" -ForegroundColor Yellow

 $i = Read-Host 'Please choose the action to continue' 

 }}

 while ($Action ="") 

 else

 {

  $i=$Action

 }

Basically, choosing Option 1 should result in 

Set-CalendarProcessing -Identity $roomname -AutomateProcessing AutoAccept -DeleteComments $true -AddOrganizerToSubject $true -AllowConflicts $false

Option 2 should result in 

Set-CalendarProcessing -Identity $roomname -AutomateProcessing None

Option 3 should simply start the script again from the point of displaying the menu

Option 4 should basically exit

Completely stuck, any help appreciated.

@coxygt  Use the switch statement.

switch($action)
{
    1 { # code goes here }
    2 { # code }
    default { # catch all }
}

@nless you need the do/while loops I'd throw it away ... 

$menu = @"
********************** Resource Calendar Delegate Booking Settings *********************
*                                                                                      *
*    1.Change delegate booking to Automatic                                            *
*    2.Change delegate booking to Manual                                               *
*    3.Check another resource calendar                                                 *

*                                                                                      *

Write-Host $menu -ForegroundColor Yellow

$action = Read-Host 'Please choose the action to continue' 

switch($action)
