Rolling Back with Office 365

talk_show_interview_1600_clr_8350A question from our Twitter feed: “@imageframeuk Can you download the old version of #MSOffice when you purchase #office365? The new #MSOffice2016 for Mac is very buggy…”

Great question.  Forgive us because we’re going to answer for the Windows platform here, I don’t have my demo Mac handy but when I get it back we’ll include Mac-specific information.

Office 365 is an evergreen, versionless service.  This means there isn’t strictly what Microsoft would call a major version although in this case going from Office 2011 applications to Office 2016 applications is a major upgrade.

There are no downgrade rights with Office 365 so it’s impossible to subscribe to Office 365 and install Office 2010 applications or Office 2011 Mac applications.  Depending on the subscription plan you have:

     1- you can control how and when future updates are installed

     2- you can disable automatic updates

     3- you can rollback to a previous update

There are limitations to this though.  Option 1 is discussed in this TechNet blog article Managing Updates for Office 365 ProPlus.

Option 2 can be achieved through company-wide policy or in the individual program.  In any Office 365 ProPlus for Windows application, select File, Account and you’ll see the update options on the right-hand side.


Option to Disable Office 365 updates

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.


Option to Disable Office 365 updates

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?
