### Adding Backup Application to Microsoft Organization

This example shows how to add a backup application to an application pool of Microsoft organization.

```
$securepassword = Read-Host "Enter your password" -AsSecureString
Enter your password: **********
$org = Get-VBOOrganization
$app = Get-VBOApplication -Organization $org -Name "New_App"
$newApp = New-VBOBackupApplication -Application $app -ApplicationCertificatePath "C:\certificate\cert.pfx" -ApplicationCertificatePassword $securepassword
Add-VBOBackupApplication -Organization $org -BackupApplications $newApp
```

Perform the following steps:

1. Specify the secure password:

   1. Run the [`Read-Host`](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host) cmdlet. Specify the message that the console will display as a prompt. Provide the `AsSecureString` parameter. Save the result to the `$securepassword` variable.
   2. Enter the password.

2. Get an application:

   1. Run the [`Get-VBOOrganization`](get-vboorganization.md) cmdlet. Save the result to the `$org` variable.
   2. Run the [`Get-VBOApplication`](get-vboapplication.md) cmdlet. Set the `$org` variable as the `Organization` parameter value. Specify the `Name` parameter value. Save the result to the `$app` variable.

3. Run the [`New-VBOBackupApplication`](new-vbobackupapplication.md) cmdlet. Specify the `Application`, `ApplicationCertificatePath` and `ApplicationCertificatePassword` parameters. Save the result to the `$newApp` variable.
