I have configured User quota + Domain quota, both seem to be working perfectly fine on both Thunderbird and Roundcube web interface but Outlook shows "Quota information Off" instead. All I can find on the subject is something about Exchange server not being configured properly but I'm not using exchange, I'm only using IMAP instead.

Is there a fix for this or is it a misconfiguration on my side?

Thanks in advance!
