Email collaboration and accessibility have improved team productivity
The valuable features include the email service, email updates, and Google Drive. People are given email access to Google Drive. The team can share manual files and work accordingly. They can access different teams from anywhere, collectively putting files, sharing them, and managing them. Additionally, the manufacturing product does not require any downgrades. It works fine and continuously for the last three or four years. Users can access their emails from anywhere in their browser without a laptop or can directly access from Gmail. This is helpful for salespeople.

Useful for collaboration and storage but improvement is needed in API integration
The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory. I think IceWarp needs to improve in a few areas. They have two types of admin consoles - a web-based one and a remote one. I'd like to see these combined into a single web-based admin console. The log reading and information system also needs improvement. The current way of showing incoming and outgoing logs isn't very clear. For new users, it's hard to understand these logs, especially compared to Office 365 and other systems with easier-to-read logs. They should also add an export option to get all logs with a single click whenever we need them.

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.

Cons

"They can maybe improve its graphical user interface. Google is not really known for having a PC interface. It is just a nice-to-have feature."
"Google Workspace does a pretty good job, so it doesn't have that much room for improvement, but what would make it even better is if its apps, for example, Gmail, could integrate with more apps, such as Evernote and specific cloud-based platforms."
"There are times the plugins or extensions in the solution do not work properly and I need to disable and enable the solution."
"It would be a lot nicer if the default Gmail came with features that we currently need add-ons for, such as tables, automatic BCC, resizing of the panel on the left-hand side, email highlighting, and configuring the display of time and date against each email."
"I would rate the stability a five out of ten."
"The product could improve the number of participants allowed in a meeting and the strength of the meetings."
"The synchronization is a bit of an issue."
"We've had difficulty using PowerPoint files in G Suite. PowerPoint has some functions that are not available in G Suite, so when you convert from PPTX to the Slides format, they don't work."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"The exchange compatibility mode is rather limited. Their technical support can also be better. They only provide online support, and there should be some option for escalating."
"The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"The solution needs improvements in security, particularly regarding document management."
"Our customers sometimes have problems receiving mail."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"We have had an issue with security."
"The tool should improve its multi-cloud feature."
"I would like to see a Microsoft schedule function added."
"The solution’s forums don't have much information or documentation on administration tasks."
"There are some security issues."
"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."
"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."
"Zimbra Collaboration's video conferencing could be improved."
 

Pricing and Cost Advice

"It's about $8.30 up a user per month."
"The pricing is reasonable."
"You pay for Google Workspace based on your usage and the apps you use, but in my case, it's free, but if I used it a lot more, I'd probably need to pay. 15GB is enough for me, but I see myself upgrading and paying the additional charges for more storage regularly."
"I can't recall the exact pricing per user for Google Workspace, but I know it's not that expensive. I'm in a mid-sized company that's able to maintain and afford Google Workspace, so it has competitive pricing, and I would rate its price as four out of five."
"2,500 Rupees per month per user."
"I would rate the pricing and eight out of ten."
"Pricing and licensing is very competitive and in some cases, cheap."
"The license is based on the number of users."

"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."
