I can confirm that I hit this bug while running 3.10.4 installed from the Ubuntu Software Center for the current LTS version of Ubuntu
$ lsb_release -rc
Release: 14.04
Codename: trusty
I had previous setup Gmail (googlemail) and a pop account in Evolution. Some recent changes to my work's exchange setup meant that pop was no longer a connection option. I disabled the pop account. Installed evolution-ews from the Software Centre and tried to add my Exchange account. Everything worked very well until I clicked the final button, which caused the window to close and seemingly no new email account to be added. This looks very much like a silent failure.
Closing Evolution and reopening it using the File > Quite or red X did not seem to change the state of things. After finding this bug via an Internet search I tried the work around of logging out from my current GUI session and logging back in. When I opened Evolution two new Exchange MAPI accounts were shown. Both seemed to work.
If people have tried to setup Exchange with Microsoft Exchange instead of using Outlook on Windows and seen this they may think it has silently failed. They may be wholly unaware that there is in fact a working mail account if they were to open Evolution agian, but why would they try when they have seen it fail?
