Backing up your email data is essential to maintaining the security and integrity of your business's information. If you are using Office 365, several options are available to help you create backups of your email data.
One option is to use the built-in data backup and recovery features provided by Office 365. It includes automatic backup and recovery of certain data types, such as email and files stored in OneDrive for Business.
