I found that the IDs stored for emails had tons of old references from previous testing and upgrades. I cleaned those out and re-loaded the server details and it worked fine. In the upgrade to v8.31 and now v8.4 I found the dashlet for email stopped providing SUBJECT. See attachment. I fixed it using this topic. The dashlet for MyTasks also does not work still in v8.4 for me. The software is still creating cache and other directories with the wrong user. There is no reason not to load a configuration with the proper owner and attributes for your server www-data or whatever. It is kind of dumb to have the user do admin work just for updating the software and find the directories and permissions are mismatched. This should be high priority and no other software requires this type of admin fixes for install or updates (that I use).
