Select Disable Updates and none of your Office applications will be updated; you won’t need to do this in each application. Somewhere in the world a puppy will start crying however, because you are defying Microsoft.
This action shouldn’t be taken lightly though; you will also not receive security patches so your products may become vulnerable. And at some point, your installation of Office will become unsupported.
Option 3 is performed by running OfficeC2RClient.exe from an administrative command-prompt and using the updatetoversion switch with the specific version you want to deploy which can be newer or older than the current version (or you may not have one installed at all). If you don’t specify a version, it defaults to the latest one. The versions only go back so far but theoretically you could deploy an older release going back a couple of years.
How will rollbacks work when Office 2016 applications are brought into mainstream Office 365?
We’ll post an update to this blog when we try it.
The last point may seem obvious and irrelevant but we have to mention it for completeness. You can of course still use Office 2011 for Mac on the device whilst connecting to the Office 365 cloud services. But this is not going to help if you’ve subscribed to an Office 365 plan which includes Office applications; who wants to pay twice for the same thing?
