Re Evolution. You may see from Synaptic PM that Evolution-data-server remains after you uninstall the Evolution app. DO NOT remove that!
See this:

Thunderbird 32bit and add-ons

Yes, the evolution-data-server is used by the Online Accounts feature which is a part of the desktop. Despite sharing a name with the Evolution app, it acts more like a library and can function independently of the mail/groupware app. It’s not recommended to remove the evolution-data-server packages from the system in order to keep this functionality and maintain system stability, as it’s a dependency of the desktop.
