Synchronization issues using Outlook 2013 with Zimbra
Zimbra Server version: Release 8.0.3_GA_5664.RHEL6_64_20130305090204
OS version: CentOS6_64 FOSS edition
We are using Outlook 2013 email client which synchronizes with the above mentioned Zimbra server using IMAP. We are facing the following issues related to synchronization with server:
1. After synchronization with Zimbra, the count of emails differs between server and outlook e.g. as per server there are 173 unread emails but as per outlook there are 169 unread emails.
2. Although the names of folders on the mail server are in German, after synchronization in outlook the folder names appear in English.
3. Certain folders cannot be deleted within Outlook e.g. 'Junk Email', 'Contact' and 'Note' (even if deleted they reappear)
Based on our research so far, we have found that Outlook 2013 uses the XLIST or LIST-ENHANCED command for IMAP and if the mail server does not support XLIST there could be problems using Outlook 2013 via IMAP:

Also, the following post has a mention that Zimbra does not support XLIST but we are not sure whether it does support XLIST or not: https://bugzilla.mozilla.org/show_bug.cgi?id=663836
Could all the above issues be related to XLIST support? Is there anything in either Zimbra or Outlook configuration that we are missing? Any help for resolving above mentioned issues will be greatly appreciated.
