"A useful tool for everyday work communication"
4.5/5
What do you like best about Microsoft Outlook?

Microsoft Outlook helps me manage emails, calendar, meetings, and tasks from one place, which makes daily work easier. It works well with Microsoft Teams and other Microsoft applications, helping with meetings, reminders, and coordination. I also find the recall or undo send option very useful, especially when I need to send emails quickly before logging out early, as it allows me to correct mistakes if required. In my work I am using it almost everyday and it is very easy to use and implement. Customer support is helpful, though response time can sometimes vary depending on the issue.

What do you dislike about Microsoft Outlook?

Microsoft Outlook sometimes becomes slow with large mailboxes, and the search feature does not always return precise results. Review collected by and hosted on G2.com.

"Customizable Features, Fast Email Organization, and Handy Microsoft Teams Integration"
5/5
What do you like best about Microsoft Outlook?

I like the features that come with this software, especially how they can be customized at a personal level for each user. It also makes it easy to organize emails and reply quickly. The integration with Microsoft Teams is very handy as well. Performance is fast, and you can simply archive emails you don’t use anymore to save space. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Sometimes you may run into issues opening the application, and fixing it can require doing system updates and repairing the mail profile in Windows. Review collected by and hosted on G2.com.

"EMAIL"
5/5
What do you like best about Microsoft Outlook?

What I like most about Microsoft Outlook is how it brings email, calendar, and task management into one organised platform. It makes it easy to manage communication, schedule meetings, and keep track of priorities without switching between multiple tools.

The calendar integration is particularly valuable, as it allows for seamless scheduling, visibility of availability, and efficient meeting coordination—especially when working with teams across different time zones.

What do you dislike about Microsoft Outlook?

While Microsoft Outlook is a powerful tool, one drawback is that it can sometimes feel overwhelming, especially when managing a high volume of emails. Important messages can get buried if folders and rules aren’t set up effectively.

Another challenge is that the interface can feel a bit cluttered at times, particularly for new users, which may create a learning curve when trying to use all of its features efficiently.

Additionally, occasional syncing delays between email and calendar—especially across devices—can be frustrating when working in fast-paced environments where real-time updates are important. Review collected by and hosted on G2.com.

"The best email manager today, Microsoft Outlook"
3.5/5
What do you like best about Microsoft Outlook?

The most useful thing about Microsoft Outlook for me is that it allows corporate communications to stay up to date, as it enables the exchange of information and the sending of documents at a corporate level. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

What I don't like is that sometimes the application tends to give nonsensical errors when it generates "sending and receiving error" without apparent reasons since upon checking, the device still has an internet connection. Review collected by and hosted on G2.com.

"Love Outlook!"
5/5
What do you like best about Microsoft Outlook?

Outlook is a great tool for communication, where you can have several emails installed at once and has so many feautures than other tools may not. I love how easy is to use it and even if you have the free version, there are so many things you can use and do. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Sometimes when a server is down, it will send all emails to the Outbox but then it won't let you get back or recover your emails that are already in the Draft section and that you can't close Outlook if there are emails in the Outbox without losing some of them.

"Seamless Outlook in the Microsoft 365 ecosystem – strong integration & helpful support"
4/5
What do you like best about Microsoft Outlook?

We use the entire Microsoft 365 ecosystem in our company, and Outlook integrates seamlessly into it. The close integration with applications like Teams, SharePoint, Lists, or Forms significantly facilitates the workday. For example, the connection between Teams and Outlook and the calendar synchronization, which allows both personal and shared team calendars to be coordinated easily, is very practical.

Outlook also offers many helpful features for daily communication, such as the delayed sending of emails or out-of-office notifications, which are also synchronized with Teams. Copilot is also a useful addition, as it greatly simplifies written correspondence and assists in formulating or summarizing messages. The basic functions of Outlook are intuitive and easy to implement, and depending on the user, the whole thing can of course be customized, which, however, requires advanced technical knowledge.

It is also worth highlighting the support: It is now significantly faster and very helpful. Additionally, the self-help videos provided and the content in the Microsoft Learn app are very helpful for better navigating the Microsoft universe and learning about new features. Outlook is indispensable in the professional environment and is used several times a day. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Due to its extensive range of functions, Outlook can initially seem somewhat complex, especially for new users. Without a brief introduction or training, many helpful features often go unnoticed or unused. Because of the many dimensions and design possibilities, the systems are naturally more complex.

"Easy Email Organization, Great Calendar View, and Impressive Co-Pilot AI Tools"
5/5
What do you like best about Microsoft Outlook?

I love how I can view and organize my emails. I also appreciate how the calendar view looks and operates and how many meeting platforms have integrations. Recently I've been impressed with the AI tools and integration of Co-Pilot. I enjoy being able to snooze emails to return to later, pin and flag. I also love how I can turn on my out of office on Teams and Outlook will automatically turn it on as well. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

The latest version does not work with mail merge which is disappointing. This is such a classic feature so I am unsure on why it is not included. I would love it if AI could read emails and draft responses as opposed to going to Co-Pilot and entering the text in for a response. The search feature isn't always the best and so that can also be a challenge. Review collected by and hosted on G2.com.

"Outlook Covers the Essentials and Integrates Smoothly with Productivity Tools Like Zoom, & Grammarly"
4/5
What do you like best about Microsoft Outlook?

For basic functionality, Outlook does everything you need to communicate effectively internally and externally. When used within an organization, its collaborative features are further enhanced when paired with Microsoft Teams. Outlook also makes it easy to integrate with other tools, such as Zoom and Grammarly. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

While Outlook excels in basic functionality, this holds the platform back from advancing with features found on other platforms, like Gmail. It took them years to implement a check to prevent sending an email when you mention the word "attachment" without actually attaching anything. There are other basic settings, like creating a 5-second delay with the ability to cancel sending an email, that are also missing. Review collected by and hosted on G2.com.
