Powershell - Add try catch block.

Can some one help me in adding try and catch block to the below code to effectively handle exceptions and write meaningful messages when exception occurs.
$o365module = get-module -name tmp_*
$msolmodule = get-module -name msonline

if( $O365module -eq $null -or $msolmodule -eq $null){
	if($O365session -eq $null -or $O365session.State -ne "Opened"){

		$user = "myown@mydomain.onmicrosoft.com"
		$password = Get-content	 "C:\temp\password.txt" | convertto-securestring
		$credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist $user,$password
		$O365Session= New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $Credentials -Authentication Basic -AllowRedirection -warningaction silentlycontinue


		$temp = Import-PSSession $O365session -allowclobber -WarningAction SilentlyContinue -DisableNameChecking

		$moduleName = $temp.Name

		Import-Module msonline
		Connect-MsolService -Credential $credentials -warningaction silentlycontinue

write-host "$o365Session already exists"

Do you need to catch specific errors? all errors?
Are you concerned over the "get-module" lines or more?

Various examples are available, but the following link should guide you directly through the process and has many good examples:


As a start, I would put your 1st 2 lines in a try{ } block adding "-ErrorAction Stop" at the end of the "get-module" lines...
Then follow with a "catch" block as shown in the tutorial...
