I had pretty much the exact same experience as @scottbomb: EWS account creation worked find for me on 14.04-15.10, but then I tried adding an EWS account on 16.04, and it repeatedly failed to appear.
After killing *all* evolution-related processes and restarting, it worked. Evolution 3.18.5.2 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evolution in Ubuntu. https://bugs.launchpad.net/bugs/1061195 Title: Evolution appears unable to create EWS or Exchange MAPI account Status in evolution-ews: Incomplete Status in evolution package in Ubuntu: Confirmed Status in evolution-data-server package in Ubuntu: Confirmed Status in evolution-ews package in Ubuntu: Triaged Status in evolution-mapi package in Ubuntu: Confirmed Bug description: Evolution appears unable to create an EW or MAPI account. All the steps proceed normally, including fetching the URL (for EWS) or authenticating (for MAPI). However, at the conclusion of account creation process, no actual account appears in the list. I've tried starting Evolution from the command line using various DEBUG_ variables and there are no EWS- or MAPI-specific errors. So I'm not exactly sure what to do next. I am fairly certain the problem doesn't lie with my corporate Exchange server, as web mail works fine and any other EWS-capable client (like the mail app in Android).
