There is no option to increase quotas in Thunderbird. To avoid storage limits, either delete old emails and attachments or change the folder where your mail is stored so that your old emails are saved in the previous folder and your new emails are saved in the new folder. Change to a new folder each time the current folder is close to reaching the quota.(see reference 1,2)

Step 1

Choose "Account Settings" under "Tools."
