I'm getting this message: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

Mozilla Thunderbird will not pull through new emails to my inbox. The message is this: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox. I've checked that I have enough disk space so not sure what the problem is or where to go to make sure the file system allows me to write privileges.

If there is a message that keeps trying to download, or only one message downloads, delete that message via the email provider's web interface.
