Time is running out for Office 2013. In April 2013, Microsoft won’t provide security updates for this venerable software any longer. It’s time to move, and if you’re a Microsoft 365 user, our recommendation is to use Microsoft 365 apps for enterprise because it’s the most functional version. If you can handle the change, it’s the right decision.
Microsoft posted a reminder that connections from Office 2013 will no longer be supported for Office 365 service from October 13, 2020. Microsoft won’t take any action to block legacy clients, but the writing is on the wall. Office 365 tenants need to decide how to replace Office 2013 by either upgrading to Microsoft 365 apps for enterprise (click to run) or switching to browser clients like OWA.
