Outlook is a Microsoft-developed information manager software that can be used to send and receive messages, manage contacts, calendar, note-taking, journal logging, and web browser. It has been used widely in both home and business life. Most people rely on Outlook.com Backup Software as their main source of communication. Their email account probably contains lots of important data; it isn't just mail you could lose. You could lose your contacts, essential email attachments, and even calendar dates if something goes wrong. So, it's essential and necessary to back up Outlook regularly in case something happens to your computer, such as a hard drive crash, failure, system corruption, etc. In the earlier version of Outlook, a Personal Folders Backup Add-in can enable you to backup Outlook manually. But it only works with the 32-bit version of Outlook 2010. It isn't available for the later Outlook versions, including 2013, 2016, and 2019. So, how do you back up Outlook 2013, 2016, and 2019? The answer is using Outlook backup software. Outlook backup software eliminates the hassle of manual operation, which will backup your Outlook account automatically and regularly.
