With the perpetual licenced versions of Office, i.e. Office Home and Business 2016/2019/2021 and some other one time payment version of Office need an internet connection to install but there after will work without an internet connection. What you loose is the security updates, but if you are not on the internet there is minimal risk.
In reply to Dr S R's post on October 31, 2022. Hi, this is Microsoft's official site for installing Office for Mac: Download and install or reinstall Microsoft 365 or Office 2021 on a PC or Mac Note a genuine Product Key for Office can be used to download Office for Mac and Office for PC. That is the same Product Key can be used for both.
Kann ich Office 2016 für Mac und Office für Mac 2011 auf demselben Computer installieren? Ja, Sie können Office 2016 für Mac und Office für Mac 2011 gleichzeitig installieren und verwenden. Wir empfehlen jedoch, Office für Mac 2011 zu deinstallieren, bevor Sie die neue Version installieren, um Verwirrung zu vermeiden.yESZ.
