How to make a powershell choice menu call back to itself?

Question

With this script, after making a choice, how to make it loop back to the prompt again until I press "Q".
I've tried While ($true) {}, it does loop but the output is not visable..
This way I don't need the Write-Host output to remind me and 2 others how to run the tool...

param( [Parameter(Mandatory, Position = 1)] [string]$UserEmail )
cls
Write-Host "  " 
Write-Host "===============================================================" -Foreground Red
Write-Host "  First connect to Exchange, then after every choice press the " -Foreground Red
Write-Host "  the UP arrow to run the script again and you do NOT need to  " -Foreground Red
Write-Host "  reconnect to Exchange again as your session is still active. " -Foreground Red
Write-Host "===============================================================" -Foreground Red

$Title = "Email Archive Menu for $UserEmail" 
$Info = " " 
Write-Host "  "  

$options = [System.Management.Automation.Host.ChoiceDescription[]] @(
"&Connect to Exchange", 
"&Mailbox Size", 
"&Is Archiving Enabled?", 
"&Enable Archiving ", 
"Enable &Auto Expanding Archive ", 
"&Start Archiving Task ",
"&Quit")

[int]$defaultchoice = 6 $opt = $host.UI.PromptForChoice($Title , $Info , $Options, $defaultchoice) switch($opt)  
{
    0 {Invoke-Expression "Connect-ExchangeOnline" }      
    1 {Invoke-Expression "Get-Mailbox -Identity $UserEmail | Get-MailboxStatistics | Select-Object DisplayName, TotalItemSize"}     
    2 {Invoke-Expression "Get-Mailbox -Identity $UserEmail | Select ArchiveStatus, RetentionPolicy, AutoExpandingArchiveEnabled, ArchiveName"}     
    3 {Invoke-Expression "Enable-Mailbox -Identity $UserEmail -Archive" }     
    4 {Invoke-Expression "Enable-Mailbox -Identity $UserEmail -AutoExpandingArchive"}     
    5 {Invoke-Expression "Start-ManagedFolderAssistant -Identity $UserEmail"}
} 

Any Ideas anyone?

Thanks!

Hello Brett,

Regarding your post, I would like to clarify some more points:

1. The expected loop should be happening to return to the wrtite-host part or the selection options?
2. if you need to return to selection options, you could refer to the sample below.

param( [Parameter(Mandatory, Position = 1)] [string]$UserEmail )
cls
Write-Host "  " 
Write-Host "===============================================================" -Foreground Red
Write-Host "  First connect to Exchange, then after every choice press the " -Foreground Red
Write-Host "  the UP arrow to run the script again and you do NOT need to  " -Foreground Red
Write-Host "  reconnect to Exchange again as your session is still active. " -Foreground Red
Write-Host "===============================================================" -Foreground Red

$Title = "Email Archive Menu for $UserEmail" 
$Info = " " 
Write-Host "  "  

$options = [System.Management.Automation.Host.ChoiceDescription[]] @(
"&Connect to Exchange", 
"&Mailbox Size", 
"&Is Archiving Enabled?", 
"&Enable Archiving ", 
"Enable &Auto Expanding Archive ", 
"&Start Archiving Task ",
"&Quit")
$a=0
while($opt -ne 6)
{
[int]$defaultchoice = 6 
$opt = $host.UI.PromptForChoice($Title , $Info , $Options, $defaultchoice) 
switch($opt)  
{
    0 {Invoke-Expression "Connect-ExchangeOnline" }      
    1 {Invoke-Expression "Get-Mailbox -Identity $UserEmail | Get-MailboxStatistics | Select-Object DisplayName, TotalItemSize"}     
    2 {Invoke-Expression "Get-Mailbox -Identity $UserEmail | Select ArchiveStatus, RetentionPolicy, AutoExpandingArchiveEnabled, ArchiveName"}     
    3 {Invoke-Expression "Enable-Mailbox -Identity $UserEmail -Archive" }     
    4 {Invoke-Expression "Enable-Mailbox -Identity $UserEmail -AutoExpandingArchive"}     
    5 {Invoke-Expression "Start-ManagedFolderAssistant -Identity $UserEmail"}
}
}
$opt=0

3. if this is not what exactly you want, you are welcome to raise your idea in the post and I would check and reply.

Best Regards,

Ian Xue
