I saw your answer to David below, but I don't know how to do step #2, which applies to me...for the non-tech oriented person. How do I "just uninstall the Office 2011"?
Hi David,
According to your description, I have known that you would like to remove all traces of Office 365 to prevent a conflict when you reinstall Office 2010. If I have misunderstanding, please correct me.
The traces in the cloud would not affect the installation of Office 2010, however, the Office subscription may have some impact on installing the Office 2010.
1.For PC: To uninstall the Office 2013 completely, please refer to this article: Uninstall Microsoft Office 2013 or Office 365.
2.For Mac: It is not that complicated as for PC, you just need to uninstall the Office 2011. Then you can reinstall the old Office version successfully.
