how to upgrade office 2010 to office 365

Click to Run GlitchesĬlick to run normally works very well, but examples do exist when things go wrong, such as the botched update of July 14 which stopped Outlook connecting to Exchange Online and caused some tenants to rollback to a previous build by running the OfficeC2RClient program (see note below). Microsoft wants customers to transition to Microsoft 365 apps for enterprise, which use the click to run technology to upload clients. Perhaps this is to emphasize to Office 365 tenants that the days of perpetual licensing for the Office desktop applications are ending.

Microsoft’s update says, “ Support for Office 2016 and Office 2019 connections to Office 365 cloud services will continue until October 2023.” This is the end of mainstream support for Office 2019 and it’s curious that they use the same date for both versions. Finally, without security updates for older clients, a higher risk exists that an attack will succeed through a weakness fixed in a current version. In addition, the deprecation of basic authentication for many connection protocols for Exchange Online means that all clients must use modern authentication. In other words, after October 13, 2020, you can continue using Outlook 2013 to connect to Exchange Online, but you’re on your own and shouldn’t be surprised if some feature stops working or the client connects intermittently or not at all. Then they said that “ it will be required to have Office 365 ProPlus (now Microsoft 365 apps for enterprise) or Office perpetual in mainstream support to connect to Office 365 services.” Now they say that they’ll will not take “ any active measures to block older Office clients, such as Office 2013 and Office 2010, from connecting to Office 365 services.” The bite is in the comment that “ legacy clients…may experience performance and reliability issues.” We Told You Things Will Break

Microsoft has softened their line a little since 2017. The original end-of-support announcement was in April 2017, so no one should be surprised at this point. They’ve just republished the notification as MC218020 to remind everyone that the date is approaching and it’s time to act. Microsoft originally published Office 365 notification MC190854 in September 2019 to advise tenants that support will end for Office 2013 client connections to Office 365 applications on October 13, 2020.
