Folder permissions lost

If you try to delete a folder with subfolders from your e-mail box, you lose the access permissions of this folder. The subfolders can be found in the trash, but cannot be eliminated from there.
Our admins have come up with a solution to this together with Open-Xchange support.

Please be advised that our helpdesk is not able to delete these folders manually for you.

Workaround Linux

connect to the IMAP-server:

openssl s_client -crlf -connect imap.mailbox.org:993

a1 LOGIN username@mailbox.org Password

Get a list of the folders. The affected folder have the attribute "/NoSelect".

a1 LIST "" ""

LIST (\HasChildren) "/" INBOX - OK
LIST (\Noselect \HasNoChildren) "/" INBOX/TEST - damaged

If you want to recreate the folder TEST, simply do this:

a1 CREATE INBOX/TEST

If you want to delete the folder TEST, you may do so in any e-mail client or with this command:

a1 DELETE INBOX/TEST

Workaround Windows

Install the OpenSSL package from a safe source as *.exe file.

Open the file. In our default installation the pathe to the executable was this C:\Programme\OpenSSL-Win64\bin\openssl.exe
