2.2.18: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted.

[Dale Gallagher]

Hello

Could my previously reported error above have something to do with the IMAP
path prefix? It's not configured on either of the previously mentioned
servers.

I see a similar error, which may be related, when trying to sync using
offlineimap.py:

Folder INBOX [acc: test_account]:
ERROR: ERROR in syncfolder for test_account folder INBOX

Thanks
Dale
