PowerShell coding in O365 - powershell

Question

I have a question regarding sample code. I am running some scripts in O365, "Running script" as below. I want to do when a PSSession enters a "Broken" state, it will pause the script, and remove broken session (Remove-PSSession ) and re-connecting PSSession (following "Re-connecting code" as below), then restart the script. I tried to write this but but I am no familiar with coding.... Can anyone help?.....
(Server 2008 R2 SP1/PowerShell)
Any help would be appriciated.
Running Script-----
Import-Csv D:\work\users.csv | ForEach {
Grant-CsConferencingPolicy $_.UserPrincipalName -PolicyName BposSAllModalityNoFT}
Import-Csv D:\work\users.csv | ForEach {
Grant-CsExternalAccessPolicy $_.UserPrincipalName -PolicyName FederationOnly}
Re-connecting code-------
$sfboSession = New-CsOnlineSession -Credential $credential
Import-Pssession $sfboSession -AllowClobber

`Import-csv D:\IDMaster\Tools\SkypeTool\users.txt | foreach {
Do {
Grant-CsConferencingPolicy $_.UserPrincipalName -PolicyName BposSAllModalityNoFT
if ($? -ne "True")
{
get-pssession | remove-pssession
$sfboSession = New-CsOnlineSession -credential $credential
Import-PSSession $sfboSession -AllowClobber }
} # End of 'Do'
Until ($? -eq "True")
Write-Host $_.UserPrincipalName "BposSAllModalityNoFT"
Do {
Grant-CsExternalAccessPolicy $_.UserPrincipalName -PolicyName FederationAndPICDefault
if ($? -ne "True")
{
get-pssession | remove-pssession
$sfboSession = New-CsOnlineSession -credential $credential
Import-PSSession $sfboSession -AllowClobber }
} # End of 'Do'
Until ($? -eq "True")
Write-Host $_.UserPrincipalName "FederationAndPICDefault"
$string = $_.UserPrincipalName + " " + "BposSAllModalityNoFT" + " " + "FederationAndPICDefault"
Write-Output $string | Out-file D:\IDMaster\Tools\SkypeTool\Modify_Log.csv -Append -Encoding default
