Describe the solution you'd like

I have two professional emails and I'd like to sync the calendars of those email using my server address and be able to edit my emails calendars within the calendar app. Currently, it is only possible to display them using my servers hyperlink but they are in read only which is useless. Unless you decide to create a linux and android desktop app for calendar, I'm force to use my email calendar instead of your app, because with my email calendar I can use thunderbird to sync and edit them accross multiple devices. Also, I find this a little anoying not to be able to sync my email calendar or have a desktop and mobile app for your calendar app because when we create a Talk meeting it goes automatically inside your calendar app and I have to invite my email address account to be able to add it to my email calendar.

Well I hope you'll consider my proposal for improvment.

No response

No file, test, or entry point is named in the request. First clarify the external calendar protocols and providers, authentication, and editing requirements; done would mean that calendars from both professional email accounts can be synchronized and edited in the app.
