Doppelganger INBOX folder is messing up my Thunderbird
 

Hi! Today I started Thunderbird and saw this:

On the website in the folder options I could see this:

When I tried to delete the ghost folders, Fastmail responded with an error:

Delete of folder 'INBOX' failed. IMAP Command : 'delete' failed. Response was : no - Operation is not supported on mailbox.

Also this ghost folder is not unsubscribable:

Any ideas? :confused:

Client version: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.7) Gecko/20100713 Thunderbird/3.1.1

Looks like the problem described in this thread:

If that is the case it should be resolved now.

Unfortunately it's not. The problem remains. After I delete it, it reappears next time I start Thunderbird and it syncs.

I deleted the greyed out inbox and the other weird folders through Thunderbird, after that they never returned. Did you delete them from Thunderbird or through the webinterface?

You can't delete them from the web interface. It returnes this error:
Delete of folder 'INBOX' failed. IMAP Command : 'delete' failed. Response was : no - Operation is not supported on mailbox

Although this orphan folder does not show in the folder list, you can see it only when you go to the folders options.

In Thunderbird it is resubscribed to every time you restart Thunderbird even after you have deleted it.

Maybe you should post in the thread I gave you earlier. According to that thread the problem should be fixed. I know my ghost folders have vanished and not returned. Sorry I couldn't be of more help.

Thanks for the update - I'm pretty sure this one is solved. It wasn't in an area of code I touched, so I still need to talk to the original programmer at CMU to understand what they were trying to achieve with that section of code. I just switched it off!

Unfortunately the problem is still present. :(

But the best part is I actually managed to hide it in the web interface (put the flag "HIDDEN" on it) and then unsubscribe in the Thunderbird (it became subscribable for some reason). Looks like a workaround, but at least I don't see it anymore.

Oh. I got rid of it. All I needed to do was to delete the sub-folder called INBOX.Trash from the web interface (and it only!), it deleted successfully and the ghost INBOX was gone as well.

Woohoo!
