Problem:

Office sets OneDrive as the default location during its installation.  This default location causes trouble for users who prefer to save to their local or network directories.  Word or Excel may prompt users for multiple authentication requests before they can save locally.

Solution:

Change the default save location.

1. Open any Microsoft Office 2016 program.
2. Click on the File menu item.
3. Click on Options.
4.  Click on the Save tab located on the left menu.
5. Toggle the check box field that reads “Save to computer by default”.  Click OK.

Problem:

Microsoft Office is vulnerable to memory corruption vulnerabilities.  Malicious emails, sent in rich text format (RTF), can provide attackers remote code execution (RCE).  In other words, RTF emails are not safe!

Versions:  

Common vulnerability and exposure (CVE) CVE-2016-0127 impacts Office 2007, Office 2010, and Office 2013.

Solution:  

1. Run Windows Updates on a regular basis.
