Windows 11 for Microsoft Office users or Windows 10 for Microsoft Office users has a chapter devoted to explaining virtual machines, how to setup a ‘VM’ and install Office. Microsoft doesn’t support installing two versions of Office on one computer and it was never a good idea even when it was supported in years past. Virtual machines are also the best way to run multiple versions of Office on the one computer.

The virtual machine can run the same or older version of Windows (Windows 8.1, 7 or earlier) that’s fully compatible with the Office release you want. That’s possible in Windows 10 or 11 using Hyper/V (except in Windows Home), VMware Workstation or other virtual machine products. The more reliable way to run older Office releases on modern Windows is using a virtual machine. How to reliably run older Office on Windows 11 or Windows 10 Note: To apply this security update, you must have the release version of Microsoft Office 2016 installed on the computer. That doesn’t mean those versions of Office won’t work, just that Microsoft doesn’t recommend it and won’t help if you try. Even Windows 10 computers with the same version of Office 2016 connect fine to Office 365. M team has done all of the proper troubleshooting and all of the DNS records are in place. Outlook 2016 would no longer connect to Office 365. ‘Not Supported’ does NOT mean Office won’t work However, two weeks ago or so I started to experience an issue on the remaining Windows 7 computers.

NOT supported on Windows 11 is Office 2013 or earlier versions of Office like Office 2010 and Office 2007.
