Quick solution, but not very user-friendly or suitable for collaboration

It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365. An additional feature I would like to see is the ability to connect from different devices. Zimbra could be more user-friendly and deploy security rules. The integration with Outlook could be better to share agendas.
