Group INBOX mailbox moved under subfolder, how can I move it back?

[HeWhoWatches]

Hi, the "INBOX" mailbox of a shared group has been moved underneath a subfolder. If I try to move it back using an IMAP client (Thunderbird, Roundcube, Snappymail), it ends up under "<group_name>/Shared Folders/<group_name>/INBOX", rather than "<group_name>/INBOX".

Is there an alternative way to move this the mailbox, I'm not familiar with JMAP, but there don't seem to be many clients yet?

May possibly be similar to #1817 which I think dealt with folder under the INBOX folder, but maybe not the INBOX folder itself.

Thanks in advance.

Hi, can you try logging into the group account directly using an IMAP client and move it?

Hi, thanks for the reply - I think I've managed it... I added the master user and tried logged in using group-account%master-account, but it returned "Connection to IMAP server failed". I then set the permission "Authenticate with IMAP" to true for the group, which meant I could login but not see any folders. As I wasn't sure which permissions should be activated or not, I set all of the permissions with "IMAP" in the name as active against the group. I could see two copies of the INBOX mailbox (tried both Roundcube and Thunderbird), one in the regular place, one in the place it had been moved to, with the same contents.

In Thunderbird, I moved the INBOX mailbox back to the correct position, ignoring the fact there seemed to be a folder already present, if that makes sense. Logging into a different Thunderbird sesssion as a regular user with permission to the group seems to show the mailbox in the correct place (i.e. only one copy, where you would expect it to be). I am not sure whether I need to leave the group IMAP permissions in place or revert them back.
