mail won't sync to icloud
i just installed the latest high sierra update 10.13.3 on my macbook Pro. Since then, mail that i read and delete on my laptop shows up on my phone and Ipad as unread. I checked ICloud mail, and the mails are also still there e.g. my laptop says 2 unread mails. Icloud mail says 146.
How do i get the laptop to sync back with icloud?
