If the decision is still not clear following an evaluation of your IT environment and communication requirements, organizations should consider the functionalities and compatibilities of Office 2019 and Office 365. While the core traits of Office products are similar, there are a few differences that IT teams should consider.
Office 2019 offers a basic Office suite, which includes Word, Excel, PowerPoint, Outlook, and Skype for Business. On Windows devices, it also comes with Publisher and Access. These programs will not be entitled to ongoing feature updates, but they will receive security and quality updates until end of support occurs on October 14, 2025.
It is worth noting that Office 2019 is only compatible with a short list of operating systems. It can be installed on Windows 10 Semi-Annual Channel, Windows 10 Long-Term Servicing Channel (LTSC) 2019, and Windows Server 2019. However, it can be downgraded to Office 2016 for free, which is supported on Windows 7 (until End of Support occurs), Windows 8.1, Windows Server 2016, Windows Server 2012, and Windows Server 2012 R2.
Since Office 2019 is licensed per device, one license indicates one installation, meaning that multiple users can use this software. This makes Office 2019 ideal for companies and workplaces with more users than devices, such as shared workspaces. Overall, Office 2019 is an exemplary choice for organizations with fewer technological or organizations with impassable restrictions that prevent cloud migration.
Office 365 offers the same suite of applications as Office 2019, but with the addition of OneDrive, SharePoint, Sway, Office Mobile, and Outlook for Android. It can also be easily integrated with Exchange Online accounts. However, one of the most appealing features of Office 365 are their monthly feature updates, which provide ongoing, complementary upgrades to Office applications.
Regarding compatibility, Office 365 can be deployed on many operating systems that are supported by the manufacturer. It can currently be deployed on Windows 8.1, Windows 7, Windows Server 2016, Windows Server 2019, and Windows 10. However, once these operating systems reach their end of support date, Microsoft will no longer support your Office 365 deployment unless extended security updates are purchased.
