If you want to see version to version compatibilities for integrations, check out Siemens PLM's Hardware and Software Certifications Integration Matrix located at:
According to it, only 2007 and 2010 MS Office is certified for Tc10.1.
You should contact Siemens PLM via their GTAC hotline or website for answers to that question. They have a stickey post at the top of this forum with links to GTAC.
I have just done an install of 10.1.2 and ms office 2013 is suported.
You need to have the 10.1.2 update however, not the 10.1.1
