I plan to use Thunderbird for different devices like laptop and smartphone with same account settings. I hope this email program has a function to synchronize the changes (incoming new email, outgoing new email, adding new folders, deletion of folders & emails, moving emails between folders calendar etc) to all devices once I use one of them to process my emails, Let's say I check email and send email on my smartphone when I am outside office. When I return to office, I open up Thunderbird on my laptop, I want it will automatically synchronize all the changes that I have done with my smartphone. Is this possible ? When I look around the top menu, I could not see anything like this. Please advise.

For people working outside or always run around, they make some appointments or set up events/task on the calendar with their smartphone. When they go back to office or home, they would need to open the attachment files from the new emails or send email with some attachment files stored in their laptop. It will be more convenient to do this with laptop on the updated emails and calendar.
