Brian, Unfortunately I'm seeing the same behavior even with this patch on my test environments.
I enabled Trusty-Proposed updates on my package manager and installed the patch with: sudo apt-get install evolution-data-server/trusty-proposed I verified through dpkg -s evolution-data-server that I do indeed have 3.10.4-0ubuntu1.1 installed. Clicking from Inbox to Calendar still freezes the client entirely for several minutes before allowing me to click back to Inbox, just as before. I restarted the system, deleted and re-added my Exchange account, but nothing seems to help. I verified this with Ubuntu 14.04 and Ubuntu GNOME 14.04.

After configuring my work Exchange account using EWS, email, contacts, and calendar reminders appear to be working with no problems. Yet, when I click on the Calendar button to view my calendar and change to Month view, Evolution completely locks up. I manually killed all Evolution-related processes using the system monitor, but re-launching Evolution takes me back directly to the Calendar, freezing the email client once again. If I wait long enough (about 15 - 20min) the email client seems to return back to normal, but will freeze again if I click Calendar once more. I was able to recreate the issue on a VM as well. I also verified the issue exists with vanilla Ubuntu Desktop 14.04 and Ubuntu GNOME 14.04. All tests were run and confirmed on 64-bit releases. I did a little research before posting and found someone had the exact same problem with Evolution running on Fedora. The original link can be found here: https://bugzilla.redhat.com/show_bug.cgi?id=1075461 The issue appears to be with the evolution-data-server component, and a patched version of the component evolution-data-server-3.10.4-3 was released to resolve the issue. I tried looking online for an Ubuntu compatible version of the patch but have fallen short.
