What is most valuable?

Since my goal was to extend my analysis, I found the additional Drive and Gmail storage to be very valuable. Next is the interroperability with Microsoft Outlook, which is a feature also used with Hotmail. I figured the 24/7 phone and email... more»

How has it helped my organization?

I have no nonprofit organization, so it has not improved anything. However, the extra space in Drive is a potential improvement in user experience because most of the people in our organization are using either a Dropbox or Drive space.

What needs improvement?

The Outlook integration or plug-in for current outlook clients is a huge area for improvement. Calendar, contact, all that can be synched needs to be managed too.

What is most valuable?

Email in Zimbra: The email application allows users to activate the Zimlets "request read receipt". For me, it's a brand new and useful support for email services, which I have not yet experienced elsewhere. Besides, the interface is very convenient for busy people while scanning the incoming messages/emails and at the same time opening them. Despite sticking... more»

What needs improvement?

Server deployment and the GUI for emails should be better.

What is most valuable?

Lotus Domino is an excellent platform for making groupware applications that are natively integrated with email. It gives you the flexibility to publish applications in the web with practically no effort if you use some of the templates... more»

How has it helped my organization?

We used Lotus Domino / Lotus Notes a lot few years ago for: * Corporate politics and procedures * Corporate phone book * Email * Workflow applications for authorization. As soon as we solved the issue of the standard, we wanted to cover in... more»

What needs improvement?

The problem with Lotus Domino is that there are no new versions of the product. The last version that I know is 9.x.

What is most valuable?

Zarafa has several very valuable features, among them a very good Outlook-like web interface. Furthermore, ZPush for talking between ActiveSync and mobile devices is a valuable asset. In addition, one is able to connect via Outlook and the... more»

How has it helped my organization?

I mostly installed Zarafa for customers. They found it to be a lightwight groupware solution with many enterprise features, such as connecting to Active Directory or OpenLDAP.

What needs improvement?

As far as I know, only MySQL is supported. It would be great to also have Postgres support, but I am not sure if this is possible in a technical way because Zarafa has very specific requirements when it comes to storing MAPI objects in a... more»
