How to fix messages not updating?

billy20

I have a strange problem with Thunderbird. I am getting an eternal "busy wheel" both on the cursor and also on the top tab that is titled "inbox". However, I can do everything in the program as normal without any slowness. I can navigate the menu, open and read messages, even write and send them.

However, none of my folders are updating with new messages. I can't send messages to archives, and new messages don't appear in my inbox. And when I send a message, I always get the error that says there was an error saving the message to Sent Mail. But the messages do get sent and received successfully.
