thunderbird misses out one email account?

I've migrated some accounts from OE to thunderbird. I have 9 accounts.
The server settings are all set to collect mail when I open TB.
It collects mail correctly from the first 8 when it starts.
It doesnt collect mail from the ninth.
When I click "get mail" it collects mail correctly from the first 8 accounts - not the ninth.
When I use the drop-down and click to get mail from the ninth account it does - it works fine.
I've put this on the mozilla forum but no answers.
Can you help?

Thanks Beichen; no the account & pw are correct - must be or it wouldnt get the email for that account when I do it from the drop-down. Yes, its complicated.

Maybe your account or your password is not correct? Hope can help you.
p.s. Your situation is a rather complicated one so it's really hard to tell what's the reason.
