Try running an Office app (e.g. Word) in safe mode (i.e. hold the CTRL key down, and then click the app's icon) if it works correctly in safe mode, the problem points to an addin conflict. In that case, I suggest you check what addins Office says are installed and disable all non-MS ones. If Office works correctly then, try re-enabling the addins, one at a time, till you find the culprit. For more info, see: https://support.office.com/en-aus/ar...3-528af4f7ac72
