Offers good user interface and seamlessly integrates with other Microsoft services
I like its user interface. I don't struggle or face any challenges while using it. The design interface is simple. I haven't had any trouble managing it for a long time. Even if I encounter a challenge or two, I can always reach out to Microsoft for help. So, overall, it's been a very positive experience. Having everything under one account was valuable. I just had to go through cybersecurity for licensing and download everything. With one account, you can download Office and use Online features directly from your Exchange. There are security solutions in place, and we take customer data very seriously. For example, if I accidentally create a forwarding rule or send an email with an image attached, I get a notification immediately. Compliance-wise, it's quite good online. We can do many things. Even if I can't click on something or upload a specific file type, it'll still be stored for compliance or investigation purposes. So, subscribing to these features. The benefits are widespread and effective communication. We use Microsoft Teams for meetings within and outside our organization. Additionally, Teams can be used for chat, allowing us to track communication and see user activity. Those are the key points that have proven to be beneficial.

One of the premium features was customized rooms tailored to the collaboration needs
Zimbra's strength lies in its individuality, and it should focus on leveraging its unique features rather than trying to emulate competitors. My organization has certified Zimbra technicians, so we believe we can utilize Zimbra certification. However, I was recently informed by Zimbra that no such certification exists. I have recently completed the test kit, and after the training, I will gain access to tickets. Therefore, if any clients are experiencing issues, we have a certified technical team available to provide support 24/7. This is how we can cater to our client's needs. I recommend Zimbra to small-scale and enterprise customers. Anyone, even those with 5 users, can opt for Zimbra. Overall, I rate the solution a nine out of ten.

Pricing and Cost Advice

"I think that the price is a little high, especially considering that Google have a similar, free email solution."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"The price of the solution is low."
"The solution is not expensive compared to other products."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The solution is competitively priced."
