Dynamics NAV 2017 Office.dll is being randomly deleted on some user's machines

To email out of Dynamics NAV 2017, the Office dll is located in the folder: c:\Windows\assembly\GAC_MSIL\office\15.0.0.0__71e9bce111e9429c. The Office dll is the only file in the folder.

In the last few days, for some, but not all users, the entire 15.0.0.0__71e9bce111e9429c folder is being deleted along with the Office dll, of course. Users are unable to email out of Outlook until someone manually recreates the 15.0.0.0__71e9bce111e9429c folder and copies the Office dll into it. Within the last week, this has happened twice to some of our users and once for others, while most remain unaffected.

Does anyone have any ideas about what could be causing this odd behavior?

Register the exact time and machine when the incident occurs and investigate if around that time any Windows-Updates or MS Office (2013) application changes have been done.

Doing a repair of MS Office fixed the issue.
