Zentyal IMAPS with Outlook 2013

[hwits]

Hi all

I have a client who has a new PC with Outlook 2013 installed on it. For some reason (and it is most probably Outlook at fault), they do not receive new mail and on occasion receive duplicate mails.

There have been various reports around the current state of IMAP support in Outlook 2013. There seems to be a huge issue with it.

I was wondering if anyone has come across this issue, and how they fixed it (besides using another mail client)?

Thanks
