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.
