Deleting a message in Horde fails with an error:
This is what the server said: [TRYCREATE] Mailbox does not exist.
The message is moved to '
Trash ' folder, according to mailbox settings.
Check When deleting messages, move them to your Trash folder instead of marking them as deleted option in Horde IMAP preferences under Options > Deleting and Moving Messages . If
'Trash folder' option is set to
'None' , disable that option or select correct trash folder.
