It sounds like there was an issue with your Windows 7 Operating System (OS), that forced an OS rebuild. If you reinstalled Office Professional Plus for Office 365, as part of your Windows OS rebuild, it is possible that the Office installation is corrupt. I would attempt to repair or re-install Microsoft Office Professional Plus on that computer.
For Office Professional Plus for Office 365 installations, the following article details step by step troubleshooting and a section titled Repair Office installation and services. To review the article click on the following link General troubleshooting in Office Professional Plus for Office 365.
I also recommend that you verify the machine has the latest updates applied by clicking on the link to the Update Center for Microsoft Office, Office Servers, and Related Products.
It is also recommended that you install the latest updates and configure your computers for use with Office 365. The following links and instructions detail that process.
