How to get rid of Thunderbird error "[NONEXISTENT] Unknown Mailbox: Trash"
I finally found the way to make this work
So that the Thunderbird will work and get all data including syb folders Follow these steps :
Browse to : tools > account settings > server settings > advanced button >
UN-check the setting : allow server to override these name spaces
(so it would not be checked! by default it is)
Press ok
Browse to : file > subscribe > press : subscribe > ok
You should then get all the folders content + sub folders etc. into your Thunderbird * I have also created a folder in Thunderbird > and checked Google > it synced
Hopefully this will help you Cheers

Every time I start Thunderbird, I get this error:
The current operation on 'Trash' did not succeed. The mail server for account [email protected] responded: [NONEXISTENT] Unknown Mailbox: Trash (now in authenticated state) (Failure).
I've figured out that it goes away if I create folders in my Gmail accounts called "[Imap]/Trash" and "[Imap]/Sent", but why are these necessary? Even if I tell Thunderbird to unsubscribe from them, it still notices when I remove the labels and starts popping up this error again.
One account also complains if I remove the "Sent Items" label.

[Gmail]/Sent Mail
, but Thunderbird still complains if[Imap]/Sent
is deleted. -
jtreser about 13 yearsThe closest answer I found is this: forums.mozillazine.org/… I have never had this problem show up even when removing my folders on the mail server next sync of Thunderbird updates them.
