ICT Manager

We decide to use Zimbra Collaboration Suite for testing functions and for use email system on production platform.

Director

Administratively, it was more expensive than other available suites for schools.

Manager - Group MarCom

The product loads very quickly and provide you with standard email functionalities.

Back then w had storage issues which I believe had something to do with the package our company has purchased.

Email was backed up frequently and could use the backups whenever we wanted.

Graphic Designer

My team and I use Zimbra for email and scheduling meetings.

IT manager

You would need a professional installation to get the Zimbra to run efficiently on your Server

All the other providers tie you into their ecosystems and bundle features that you might simply never use.

IT Planning

Also, the cost if the licenses is cheaper than other options like Exchange.

Technician

The application for mobile devices has some flaws, among them, the loading of some thumbnails of the files that take a while.

The cost is one of the pros of Zimbra, specially if you need only the mail server.

we used to send the bill to all the clients and work well

Zimbra work fantastic, is very stable and well suited for relays server.

DevOps Engineer

Zimbra's documentation tends to be scattered, and when you do find it, you'll see that Zimbra makes its own little versions of every open source product it uses.

It is a very simple email and calendar management system.

intern

Zimbra is a BSP hosting partner because of its flexible deployment and virtualization readiness.

Freelance 

The assistance is kind, punctual and courteous and their salesmen are very good.  

Vmware Vsphere and KVM hypervisors are also fully supported.

When it worked, Zimbra provided our users with a decent experience that wasn't completely replicated once we switched away from it.

We can use Zimbra desktops to obtain Zimbra experience.

Sync your Google, Yahoo!, and Outlook calendars.

Team Leader

In addition, unlike other email companies, Zimbra's technology never locks me out.

Easily collaborate with your team and share documents.

Office Manager

Group Leader

Its an open source server for email and web client which is designed for browser based interface.

Infrastructure Lead 

Associate Application Consultant

If the auto-filing options are available for the online services, that will help me out a lot.

The compatibility with multiple devices and browser is the best feature of Zimbra.

Manager, Infrastructure Services & Telecom

The deployment was easy, I was able to easily connect the server to our LDAP server and import all of our users.

Volunteer Relations Coordinator

There aren't too many features within Zimbra, either, as compared to competitors such as Outlook.

Quantitative Analyst

It is somewhat unpolished and could produce strange from-end errors, but besides that there is not much to complain.

I assume if this had been an outage and had called in rather than only email my request, I would've received a faster response.

Administrative assistant

Due to the product being open source, who defines the support is the person who implemented the software.

I find it easy to use, and I like some of the features that they overall, but overall I don't find it the best email software out there.

I can say its really cheap compare to other email servers.

Lawyer

I am happy with the service, and would like to continue purchasing this service.

The most that i like about Mivrosoft Outlook is that im able to send and receive email messages, manage my calendar, store names and numbers  of my contacts and clients and i can track your tasks.

App Developer

I liked Outlook’s unified inbox, strong calendar integration, and reliable email organization—making scheduling, reminders, and communication easy across work and personal accounts.

Overall it is better than gmail for work, because there can lot of back and fourth in work emails and Gmail is very bad if you're going through a big long thread of email, Gmail will confuse which email came befor which one while in outlook it is very organised where the thread emails shows up in sequence of the time it came in your inbox.

I like Microsoft outlook as my work email , i find it better than gmail for work purpose also with the way Teams has improved in the past , you dont have to rely on external tools for collaboration so microsoft outlook package is great.

Curriculum Designer and Trainer

Overall outlook is a powerful e-mail tool that responds to how you read your emails and it gives you the ability to customize your in box.

Professional Development Lead

I wish my Microsoft Outlook has a larger storage capacity. Since it also hides some of the older emails, sometimes those gets lost or forgotten when I didn't get a chance to delete it.

Paralegal

My favorite feature of Microsoft Outlook is it's ability to integrate seamlessly into the software my law firm uses which makes my job infinitely more manageable.

Administrator

The interface can feel cluttered and less intuitive than some newer email platforms, and performance can lag when managing large mailboxes.

I enjoy using it daily to keep all of my files in order and I enjoy all of the tools that I am able to use.

Insight Manager

great for organisation everything - the way it links to PPT, Word, Excel etc. is great to sending work to colleagues and getting / sending notification when comments or changes are made.

Systems Analyst Trainee

It's seamless when scheduling meetings within the dept and the color-coded calendar makes for easy understanding with everyone's busy schedules.

Instructional Designer

I like the integration with Microsoft 365 and its tools, including calendar, contact management, and tasks.

Sales Manager

Microsoft Outlook helps with all my work documents that are sent through Microsoft teams and to my email to keep them all in one spot.

Microsoft outlook has been around for a while and everytime, it does not cease to improve my work in terms of operability, connectivity, collaboration, and efficiency in all.

Safety Manager

Microsoft Outlook helps keep me on task through its important emails, calendar, and frequent reminders.

Case Manager

Something I like least about Microsoft Outlook is that when I add contacts on my computer, they do not sync to the email contacts on my phone that uses the same Outlook.

Meta Ads Specialist

However PST files love to corrupt, search crawls when mailbox is huge, and too many panes (people, todo, feed) clutter the screen, so clarity drops when you’re sprinting through emails

Outlook is reliable and feature-rich for email and calendar, but can feel slow and complex, especially when managing many messages and settings.

Teaching Assistant

The layout of the Outlook mail app and website is great, it is highly customizable, in terms of the theme as well as any signatures that you might want to add.

Event Planner

It’s also quick to set up recurring client calls and internal check ins and you can simply attach documents to calendar invites to remain in context.

Projects Manager

The calendar is essential and setting up signatures for different users and out of office messages save a lot of time.

Outlook is one of my staple e-mail apps, I use it daily and feel microsoft has made several great changes to make the overall user experiecne better than the legacy outlook application that had reached end of life before being replaced.

It's ability to integrate into other software, to create rules, away messages, and the personalization features are unmatched.

IT Service Desk Analyst

Microsoft Outlook is also a great way to effectively collaborate with a team, whether that's communicating via email, or arranging meetings with each other to discuss things further.

Intake Coordinator

Email and calendar management are very well integrated, making it easy to keep track of meetings, deadlines, and important conversations.

I can drag mails to tasks, schedule meetings right there, and the calendar pops reminders that actually show up on time

Sales Development Rep

The ability to schedule meetings, set reminders, and manage communications all in one place significantly boosts productivity.

System Admin I

Cluttered interface, slow performance, unreliable notifications, and missing features like offline message saving or advanced rule customization

Credit Specialist

I can use it for email, to manage my schedule, keep track of documents and creating agendas.

Loan servicing representative

The con on Microsoft Outlook is a large file can take forever and cause delays .Outlook also can freeze at times.

Marketing

It’s not the flashiest email client, but its stability, integration with Microsoft 365, and comprehensive feature set make it hard to beat for business use.

I like being able to easily access my shared folders, folders that I have created, and search for emails that I have saved quickly.

shipping and receiving

The thing I like the most when I am using Microsoft Outlook is the fact that I can do so many different customizations to my liking.

I like the ability to customize the interface so that you are not always staring at a blank white or gray screen.

Pharmacist

I use Outlook at different job sites across the province and it feels familiar and seems to be faster and is easier to log in and just access messages than Gmail

There is a lot of customisation, which is great to some degree, but at the same time I need to use three different email addresses per day.

It helps me daily to track all my meetings and gets updated in real time.

My only gripe is that if I am deleting an email from my inbox at the same time a new message appears, often times the new email gets deleted instead of the email

Client Service Coordinator

For example, if there are too many images, I wish it would notify me so I can adjust appropriately, versus sending it out and there being an error.

Legal Case Manager Assistant

I love the options on how I'm able to differentiate my availability during the times set on my calendar.

The only reason we have yet to change our provider is the time off-line we would need to make the shift. While, there is value in the cost of the product - it has very little real value.

Operations Manager

It gives me access to my calendar and my meetings in Teams.
