can anyone give some tips on how this can be done?
It's not easy. :-)
But it has been done by a very few ambitious, determined, and patient people over the years.
I would suggest starting by reviewing these previous conversations, and note that you'll need to modify WSUS to accept the larger CAB file size.
Creating an Office 2007 package
Deploy Microsoft Office 2010
Push out Office 2013 install??
Package size limit?
I was able to create a Microsoft Office 2010 deployment using Patch Manager a few years ago. I was able to include several patches, but had some difficulty using the activation for office after the install was complete. Also, I ran into size issues with Patch Manager since the complete package with patches was about 1 or 2 gigs. I also phased the deployment to small groups at a time so as not to saturate the network. The key points to deployment for Office 2010 is use a custom config.xml file in the ProPlus.WW directory AND make sure you have enough bandwidth to deploy.
This is my first time trying to deploy Office 2010 via Patch manager. Can you give me some tips on how to use a custom config.xml?
