<br>
Storage Server fails means that roundcubemail is not able to community<br>
or authenticate with the backend (aka imap server port 143).<br>
<br>
I would check the following points<br>
* is guam running (systemctl status guam). Guam is the imap proxy <br>
sitting<br>
in front of cyrus.<br>
* is cyrus-imapd server running (process table)<br>
* do you see any authentication related error messages from cyrus<br>
* is kolab-saslauthd and/or dirsrv running correctly?<br>
* is kolabd running?<br>
<br>
Another thing could be that guam/cyrus is running but the kolabd server<br>
has not created the mailbox yet. Restarting/Checking kolabd might help<br>
(as well checking the pykolab logfiles). Otherwise run "kolab sync" via<br>
cli to execute the mailbox sync/creating run manually.<br>
<br>
