SharePoint Online: Co-authoring with differing versions of Word
Great question, and yes. It would be great to get someone from MS describe the optimal configuration and also cover that error and other gotcha's. Having files locked from editing because someone is editing it and that someone is you is incredibly frustrating.

What is required to have real-time (with clicking save) co-authoring Word, do you have to use Word Online? How about Excel?
Hello Vanessa
If user is on Office 2013 for optimal co-authoring experience and successful interaction i would recommend two things.
1) For users Running Office 2013 make sure that you have implemented the ADAL fix recommended by https://support.office.com/en-us/article/Enable-Modern-Authentication-for-Office-2013-on-Windows-devices-7dc1c01a-090f-4971-9677-f1b192d6c910?ui=en-US&rs=en-US&ad=US. It will resolve any authentication issues.
2) Make sure sites are granted full trust.
Here are additional troubleshooting steps from Microsoft.
