Before I download the installer image file and attempt to install Office 2019 for Mac, I want to be sure that I don’t lose any of the account settings, offline emails, folders, etc. Microsoft 365 plans include premium versions of these apps plus other services enabled over the internet, including 1 TB of cloud storage with OneDrive and Skype minutes for home use 1. I currently have MS Office 2016 Home & Business installed on my Mac Pro, and I recently purchased Office Home & Business 2019 to update it. However, there are no upgrade options which means if you plan to upgrade to the next major release, you'll have to buy it at full price. Office 2019 includes apps such as Word, Excel, PowerPoint, and Outlook. Office 2019 includes a meaningful subset of features that are found in Microsoft 365, but its not part of Microsoft 365. Office 2019 is sold as a one-time purchase, which means you pay a single, up-front cost to get Office apps for one computer. Office 2019 (for both Windows and Mac) is a one-time purchase and does not receive feature updates after you purchase it. Full pricing information can be found here.
