For all the Zimbra customers out there, we wanted to let you know that the Briefcase application in Zimbra is here to stay. For the passionate Briefcase users, please let us know how we can improve it for the future. Please log requests in Bugzilla or post here.
Zimbra will also continue to integrate with other file sharing applications including VMware Horizon and Dropbox. VMware Horizon will provide more advanced sharing capabilities and sync across clients and we are currently working with them on an integration. For those of you that cannot wait and are currently using Dropbox, we have the Dropbox Zimlet available in the Zimbra Gallery Dropbox Zimlet | Zimbra :: Gallery.
