Google Vault (GV) is a core application of G Suite that allows users to retain their data and then search and use them according to their purposes. It is quite similar to Google Drive, but there is one major difference. While Google Drive allows backup, GV on the other hand does not. This is where the problem lies. In some cases, you need to download emails in Google Vault in different formats such as PST and MBOX. This is yet another significant difference between Google Vault and Google Drive. Downloading Google Vault emails in PST and MBOX format is not an option available in abundance. Therefore, we are going to use a program called Systools Gmail backup, that is going to help us download emails in every major format required. Follow us.
