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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The initial setup is easy because it's all pre-configured."
"Google Mail lets you link a task to a specific email and add a reminder. That's helpful for reviewing your schedule. It's based on Slack, so you don't have these folders like in Microsoft mail. Using Slack instead of folders is a bit more intuitive. It's easier to find again a specific email than using Microsoft Suite. If you misplace things, it's much easier to find them because of Google's search capability."
"In terms of email, I could probably do the same things with other programs, however, I find 90% of my usage is Gmail."
"The most valuable feature of the solution is email."
"They are launching more and more features for mobile, which I understand our customers appreciate."
"The initial setup is simple."
"The valuable feature of Google Workspace is its integrated environment where everything is pre-integrated, like chat and document sharing in Gmail."
"I use Keep to assign tasks to a team of programmers, which is very easy."
"The product is used very extensively in my company since we have around 1,500 users using it. Also, there is no requirement for any administrators to manage the product by the people who own the solution."
"The groupware module is the most valuable feature."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"It has great communication capabilities for team chatting and web conferences."
"The solution's voice services work well for our company."
"The solution has a very good log-in to the UI when compared to other solutions."
"IceWarp has multiple applications that are easy to use for many people."
"The TeamChat feature has been really good for our email management. It lets us collaborate, share files, and invite guests like Google Spaces or Microsoft Teams. I like the two-factor authentication for security. However, they need to improve their document collaboration tools, as their Word, Excel, and PowerPoint features are basic compared to Microsoft and Google."
"The configuration is simple."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"The solution is easy to implement."
"The web interface is powerful and easy to use."
"Good email solution and it's open-source."
"The stability is good and keeps getting better with each new update."
 

Cons

"The cost could be improved. It can sometimes be a bit confusing figuring out how we are actually being charged."
"The problem with the presentation is that if you upload a Microsoft PowerPoint presentation and you convert it to Google presentation, the slides or pictures, their images are not editable. You can't edit the slides that you brought in. They're just images."
"Google could integrate Gemini AI with Google Workspace to enhance user experience."
"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."
"One area of improvement for Google Workspace is the Google Meet functionality. Currently, users cannot upload files directly through Google Meet; instead, they have to share links via Google Drive, which adds unnecessary steps and complexity."
"Some concerns over security, but there are moves to address this and provide admin tools to secure content and adhere to data protection regulations."
"In the next release, I would like to see more encryption of documents, mail, and things like that. There should be a better way to encrypt mail and documents that are pushed through this system. That would be some improvement or additional features that could be good to have."
"G Suite could offer something a little more solid in terms of chat — something that is a little more like Slack and integrates with everything. But, unfortunately, the chat is very basic there. It doesn't offer that many features and feels like it doesn't belong there."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The solution needs improvements in security, particularly regarding document management."
"The solution should improve the mailing list feature. Google has a similar feature where you can automate sending files to different people in a sequence, but that feature is no longer available in the current version of IceWarp. Other features may also have been removed in the current version."
"The tool's configuration capabilities are not straightforward. Apart from that, if I want to archive emails into a vault so that they can be retrieved again later, the integration doesn't work, and IceWarp crashes."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"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’s forums don't have much information or documentation on administration tasks."
"I would like to see a Microsoft schedule function added."
"The solution could improve by making it easier to use."
"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."
"They should enhance its online meeting features."
"The installation is not straightforward, it can take two days for the full implementation."
"There are some security issues."
"Zimbra Collaboration's video conferencing could be improved."
 

Pricing and Cost Advice

"G Suite and Microsoft Office 365 offer products with similar functionality at several different price points. Zoho offer a more extensive range of products and attempts to provide all the applications required to run most small and medium-sized businesses."
"2,500 Rupees per month per user."
"It's cheaper to run a couple of users in a Google platform than what it would be with Microsoft Exchange."
"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."
"The pricing is comparable, it's pretty decent."
"The price per client within the business is too high."
"There are several areas where a G Suite implementation can reduce costs: lower license fees than some competing products, reduced hardware, and IT support costs."
"The pricing is a bit on the higher side than normal. For a basic Google account it costs $100, but Enterprise is %150."
"There are various licensing plans available based on geographic zone."
"I would rate the pricing and eight out of ten."
"The solution is inexpensive which is its main benefit."
"Our licensing is on a yearly basis. There were no additional costs."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"Pricing and licensing is very competitive and in some cases, cheap."
"The license is based on the number of users."
"I don't see any challenges for the Indian market. For example, 1 GB is available for around 399 INR, and 2 GB for 499 INR. They offer a range of plans, from basic to professional and enterprise, with multiple features. IceWarp's aggressive pricing is competitive compared to other market solutions like Zoho and Microsoft. One significant advantage is that IceWarp does not impose user capping like Google and Microsoft, which allows for substantial cost savings and flexibility in user conversion."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"The solution is not expensive compared to other products."
"Zimbra Collaboration offers a good price-to-feature ratio."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
"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."
