- Question from Microsoft Community

As you know, in order to keep your data safe and up to date, you need to make backups frequently. Keeping a backup can help you in several ways such as exporting critical data or moving data to other important platforms or even moving to a new system where you need to import data.

It can also help you to keep Outlook data files away from any corruption when there is any virus or malware attack on the system. Thus, backup is always the best option to handle Outlook data. Backing up Outlook in the traditional way can be quite laborious and time consuming, so many users want to find a solution to automatically backup Outlook 365.

Can Outlook 365 Automatically Backup All Data?

Auto Backup Outlook 365

As we all know, Outlook has some built-in features that allow us to manually set up a backup to back up our Outlook data files to a different location or to a cloud storage service. However, even these features have certain limitations and restrictions:

  • When you use the Auto Archive feature, you cannot backup items such as Notes, Drafts Folder, and Contacts as the Contacts folder doesn’t have an archive property.
  • Similarly, using the Import/Export feature, you can manually backup PST files every time, but you can't choose to select folders and can only backup the folders you need.
  • Personal Folder Backup Add-in is available only for Outlook versions before 2010, it is not compatible with newer versions of Outlook. With Outlook Personal Folder Backup, you can only backup your PST files, which sometimes takes up a big chunk of space.

In short, Outlook 365 cannot automatically backup all your data. To avoid this situation and overcome the limitations of these methods, use a professional tool that can work well with all Outlook versions without any hassle. With the help of a reliable Outlook backup tool, you can easily perform Outlook 365 automatic backup.
