I will starting a project deploying office 365 ProPlus in an enterprise and seeking assistance on following:-

customer Scenario:

1- SCCM 2012 R2

2- Active Directory 2008 R2

3- Mix of Office 2010/2013 professional installed on client machine

I would like to understand following:-

Installation Scenario:

1- on Office 2013 installed desktop, can I run office 365 Proplus installation on top of existing office 2013 client (standalone)

2- on Office 2010 installed desktop, can I run office 365 Proplus installation on top of existing office 2010 client (standalone)

Uninstallation Scenario:

1- if existing Office need to be removed before deploying cloud Office, what is the best procedure to automate the installation of existing office client from desktop pc either using group policy or SCCM.

I am looking for fully automated uninstallation procedure irrespective of existing Office version or separately for Office 2010 and Office 2013 either using group policy or SCCM.

Hi Farrukh,

For the installation scenario, you can run the latest version of Office (click-to-run based version) side-by-side with an earlier version of Office that is already installed on your computer. That is to say:

MSI-based version of Office 2013 on a system with Click-To-Run-based version of Office 2013 (Office 365 Proplus ) installed side-by-side is not supported.

MSI-based version of Office 2010 and Click-To-Run-based version of Office 2013 (Office 365 Proplus ) will run side-by-side, but we don't recommend this for a long-term use.

Regarding the uninstallation scenario, you can automate the uninstallation of existing Office via command line. It will look similar to the following example:

\\server\share\Office12\setup.exe /uninstall ProPlus /config <pathtoUninstallconfig.xml>\UninstallConfig.xml

You can easily integrate this command line into SCCM or a Group Policy computer startup scripts.

Here is a great blog post about how to upgrade to the latest version of Office, you might want to have a look: http://blogs.technet.com/b/odsupport/archive/2014/11/03/how-to-uninstall-office-2010-and-move-to-office-2013-click-to-run-or-volume-license.aspx

Hope this helps.

Hi Ethan

"MSI-based version of Office 2013 on a system with Click-To-Run-based version of Office 2013 (Office 365 Proplus ) installed side-by-side is not supported" not supported meaning it will allow to install or install will succeed but Microsoft will not support any problem/issues.

Thanks

Hi Farrukh,

You can finish the installation, but probably will encounter unexpected problems during the use. We do not recommend this combination.
