This is the first time I have implemented a room video conferencing solution that didn't feel like torture. Right away from the unboxing of the equipment and the clear instructions I was satisfied. The full Teams Room kit had multiple options for cabling and detailed configuration options. It immediately connected to our Office 365 environment and we were live very quickly. We had one hiccup with the pass through on the Tap system but there was a firmware update available already that resolved it immediately.
Zimbra is great for an email system for a medium or large organization with appropriate IT staffing. The system is easy to use for end-users, and has a fantastic web interface. Unfortunately, it is overly complex, when considering staffing requirements and price, when compared with Office 365 or Google Apps for smaller organizations. For other education customers, it is hard to compete with Microsoft and Google providing their services for "Free" now though
The password change is not activated when you access by IMAP, Pop3 or Exchange sync. You have to know that the password change is required and you must go to the website to do so.
The management of mail rules should have more checking options.
There should be more applications compatible with Zimbra, the ones that appear in the Zimlets.
Overall, we were satisfied with the implementation. We perhaps should have spent more time consulting with Zimbra or others regarding best practices but as we got to know the system better we were able to make changes relatively easily after the fact.
The Rally units are a significant improvement on the Dolby units, providing a more capable interface with better screen sharing capabilities. The units are significantly cheaper than the Cisco units, however they do not offer the remote management capabilities of the Cisco units.
We selected Zimbra because it has a lower cost in the market, offers more development features for its open source, has a very easy to use interface and adjusts to the needs of the company.
Since all of our ROI studies and strategies are performed at the corporate level, I'm really not sure what positive or negative impacts Zimbra has had on our overall business objectives. I can say that at least one positive impact it has on my business objectives, in the medical record department, is the ability to be as paperless as possible.
