"Seamless Enterprise Communication and Scheduling with Microsoft Outlook"
5/5
What do you like best about Microsoft Outlook?

What I like best about Microsoft Outlook is how seamlessly it manages enterprise-level communication and scheduling in a single place. Its advanced calendar management, meeting scheduling, and deep integration with MS Teams make it extremely easy to track daily tasks and coordinate with teams and clients in a corporate environment. Features like robust security controls and the Focused Inbox also significantly boost daily productivity. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

While Microsoft Outlook is an essential enterprise tool, one minor drawback is its high resource consumption, which can occasionally impact system performance when handling large mailboxes alongside multiple integrations. Additionally, setting up custom third-party integrations and add-ins can sometimes involve a bit of a learning curve and requires administrative overhead to configure smoothly across a large corporate team.

"Reliable, Familiar Outlook That Just Works"
4.5/5
What do you like best about Microsoft Outlook?

After using Outlook for years, its reliability is what keeps me coming back—it simply works day in and day out. The interface is familiar, so I never have to relearn how to do the basic things. For personal email, that kind of consistency matters a lot to me. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

The main downside I’ve run into is performance—Outlook can feel slow or a bit laggy at times, especially when it’s loading or syncing my personal mailbox. It’s not a dealbreaker for me, but a lighter, faster overall experience would make it even better. Review collected by and hosted on G2.com.

"Foundational Email Tool"
5/5
What do you like best about Microsoft Outlook?

Outlook is great for me because it integrates with the rest of the Microsoft environment like Teams and the M365 suite. It’s very easy to schedule meetings and the main feature, sending and receiving emails, has been really perfected over all of this time. They keep adding new features and integrations, so it’s constantly improving. I’m so used to it now that it’s like 2nd nature to use all of its tools and features. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

I think there are a few features missing from the new version of Outlook (such as the voting buttons for emails) that were in the old version. Some of these features were replaced with new ones (in the case of the voting buttons we now have polls), but I think they still have some work to do in order to get the new Outlook up to where the old one was.

"Calendar Auto-Sync and AI Email Summaries Make Scheduling and Inbox Triage Effortless"
5/5
What do you like best about Microsoft Outlook?

UI/UX: Clean, familiar, unified inbox view.

Integrations: Deep with Teams, SharePoint, Power Automate.

Performance: Classic is fast; New Outlook lags on notifications.

Pricing/ROI: Prices rising July 2026, but AI/security now bundled in.

Support: Good docs, quality varies by tier.

AI: Copilot summarization + calendar-aware chat — strongest feature. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Notifications are painfully slow — New Outlook can take over 10 seconds just to open an email from a notification. Mail Merge is weak, and a lot of "new" features barely work if you're not on a Microsoft-hosted mailbox. Honestly, Classic Outlook still feels more reliable overall.

"Microsoft Outlook Keeps Email, Calendar, Contacts, and Tasks Perfectly Organized"
4.5/5
What do you like best about Microsoft Outlook?

What I like best about Microsoft Outlook is that it brings email, calendar, contacts, and task management into one place. It makes it easier to stay organized, schedule meetings, and manage priorities without switching between multiple applications Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

I wouldn't say I dislike Outlook, but one area that can be improved is how quickly the inbox can become cluttered when managing a high volume of emails. It sometimes takes time to organize messages and ensure important emails don't get buried. Fortunately, features like folders, categories, rules, and Focused Inbox help manage this effectively once they're set up Review collected by and hosted on G2.com.

"Well-Organized, Microsoft 365-Friendly Email Editing That Feels Like Word"
4.5/5
What do you like best about Microsoft Outlook?

It’s well organized and works great in a work environment. The best part is that it works with Microsoft 365, which is helpful in so many ways. Editing text—like you do in Word—is such a relief, especially when I’m writing emails and want to express my intention clearly. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

The only downside I’m facing right now is the notification badge. While I’m at work, it’s important to have the badge because it clearly shows how many emails are pending. However, after trying everything and doing some troubleshooting, nothing has changed—it’s still the same. Review collected by and hosted on G2.com.

"Microsoft Outlook – A Reliable and Organized Email Solution"
5/5
What do you like best about Microsoft Outlook?

What I like most about Microsoft Outlook is that it's simple, organized, and easy to use. Unlike Gmail, where long email conversations can sometimes get grouped into a single thread and become confusing, Outlook makes it much easier to view and manage emails. I can quickly find emails from the same sender, check them by date, and track conversations without getting lost.

The search feature is fast, folders and categories help keep my inbox organized, and the calendar integration makes it easy to manage meetings and appointments. Overall, Outlook provides a clean and professional email experience that helps me stay organized and work more efficiently. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

While Microsoft Outlook is a great email platform overall, there are a few areas that could be improved. Sometimes it can feel a bit slow when opening large mailboxes or searching through older emails. Occasionally, email synchronization takes a little longer than expected, especially when switching between devices. Improving the speed, simplifying some settings, and making the interface a bit more intuitive would make the overall experience even better. Review collected by and hosted on G2.com.

"Gen Z-Friendly Interface with Powerful Features That Beat Gmail"
4.5/5
What do you like best about Microsoft Outlook?

Seriously, if I have to talk about the best thing about Outlook, it’s its interface. It feels very Gen Z. Apart from that, I think it’s far better than Gmail. It provides more options than Gmail and has more features. In our college, all emails are created on Outlook, and it makes it easy to mark important things. It also keeps messages away from spam and helps you stay organised compared to Gmail. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

What i feel the thing that I dislike about the ui ux is it's interface feel cluttered mainly with reading paneer and folders , finding some email take more clicks than expected . Apart from this the its connects with most microsoft apps but it's non integration with some non microsoft apps feels less seamless . Performance - outlook feels slow when loading large mail boxes , many advanced features are tied up with Microsoft 365 which cause it more expensive for student . If you only use Outlook for email it will be less compelling compared to other apps , Account issues often required searching through document rather than direct suppo ai feature like copilot is interesting but not available for all user rt Review collected by and hosted on G2.com.

- Calendar helps me track sessions and meetings easily.

- Search and Filters make finding old mails and reports quick and easy.

- AI Summarizes long mails in short points. Review collected by and hosted on G2.com.

"Outlook: All-in-One Email and Productivity Hub with Seamless Microsoft 365 Integration"
5/5
What do you like best about Microsoft Outlook?

It is a comprehensive email and productivity platform that brings email management, calendar scheduling, contacts, and task tracking into a single application. One aspect I appreciate most is its clean, professional user interface, which provides easy navigation across emails, calendars, contacts, and tasks without switching between multiple applications.

From a performance perspective, Outlook handles large mailboxes efficiently. I have been using Outlook for the last 2.5 years, and I can still access my old emails from when I started as an intern at my current company.

Outlook’s integration capabilities are another major advantage. I can easily connect it to Microsoft Teams, schedule meetings from there, and it automatically sends notifications to other team members through Outlook. I can also quickly check in Outlook who accepted the invites and who didn’t.

When it comes to pricing, Outlook offers strong value as part of the Microsoft 365 subscription, since it is bundled with widely used productivity applications such as Word, Excel, PowerPoint, Teams, and OneDrive.

The AI features also help me correct my mistakes in emails by auto-suggesting changes while I’m writing. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Microsoft Teams is a powerful and feature-rich platform, but there are a few areas where I think there’s room for improvement based on my day-to-day experience.

I feel the email organization could be improved, because it becomes difficult to work with multiple folders, shared mailboxes, and long email threads. Important messages can sometimes get buried within conversations, which makes it challenging to quickly locate key information. Additionally, managing large email chains with multiple participants can feel overwhelming, particularly when conversations stretch across several days or weeks.

Another frustration is the occasional synchronization delay between devices. Many times, I receive an immediate notification on my mobile but see a delay on my laptop. Other times, I get a quick notification on my laptop but the mobile Outlook notification is delayed. This inconsistency can definitely be improved. Review collected by and hosted on G2.com.
