Also, did this start happening before or after updating to 7.2.2.0?

I do believe it did start to happen once 7.2.2.0 was released. Checked with the link provided and the Microsoft desktop apps is not listed. 

Try installing the older 7.1.4.2 version to see if that helps. To download  7.1.4.2 and install it. You do NOT need to uninstall 7.2.x.x first, just backup your EW Profile (which one should be doing regularly anyway) and then install 7.1.4.2. Download links for 7.1.4.2 are below along with information on Backup Up your profile(s).
