Gmail has restrictions on the number of simultaneous email connections to cache. GMail enforces such restrictions, among other providers. This is generally done to prevent abuse and for security reasons.

The default in Thunderbird is 5. Try changing it to a lower number.

This setting can be found under Tools > Account Settings -> Server Settings -> Advanced -> IMAP -> Maximum number of server connections to cache.

Apparently there are other specific settings configuration needed for proper IMAP service on Google.

Take a look at their IMAP setup help article, it mentions:

  • Setting browser.cache.memory.capacity to 30720
  • Setting mail.server.default.fetch_by_chunks to false
  • etc.

If you account a Google Apps accounts? Apparently that needs different credentials.
