Connect-Azure-PowerShell if there is no existing Connection.

By Using MsolService to connect to Azure PowerShell, could be annoying time to time if unable to validate existing connection. The simple function below will just do that. To make below function work, you will need to adjust “$company” variable to ensure it fits into your environment. Rest of the function is pretty easy to understand.

Check If Module Exist

Here is simple PowerShell script to check if any given module exists or not. We will be using try and catch block to determine the existence of AzureAD module

# Check If module exist $module = 'AzureAD' try {     Import-Module $module -ErrorAction stop     Write-Host 'Module exists' -f Green } catch {     Write-Host 'Module does not exist' -f red -b Black }

There are other ways to accomplish same results. One other way of doing it would be

#(1)_.Assign Vars $checkModule = 'MsOnline' $List = (Get-InstalledModule).name #(2)_.Check if Module Installed if ($List -contains $checkModule) {    Write-host 'Module is installed' -f Green -$checkModule } else {     Write-host 'Module is not installed' -f Red -$checkModule }

Another way of checking doing same check;

#(3)_.Check if Module Installed if (!($List -contains $checkModule)) {    Write-host 'Module is not installed' -f Red -$checkModule    } else {    Write-host 'Module is installed' -f Green -$checkModule }
