Outlook helps us run the business. It supports communication with clients and stakeholders, and the built-in AI tools, along with a variety of other tools, make day-to-day work easier. The best part is the Outlook ecosystem, which keeps all the required tools available both on the computer and on the phone. MS Teams integration and copilot have been super helpful.

"Microsoft Outlook: Great Integration and Features"
4/5
What do you like best about Microsoft Outlook?

What I like most about Microsoft Outlook is how it quietly fits into my daily routine. I depend on it daily for emails, calendar, meetings, and reminders as all these are in one place, and over time it becomes very easy to stay organized. The search is dependable, the calendar helps avoid scheduling mistakes, and the integration with Teams and Office tools feels natural. it just works for me as its stable, familiar, and something I can rely on every workday. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

What I dislike about Microsoft Outlook is that when my mailbox gets heavy, it tends to slow down and becomes less responsive. The search usually works, but when it misses an email I know exists, it’s really frustrating. It does the job, but the experience can feel more complicated than it needs to be. Support responses often feel generic and it usually takes longer than expected to reach someone who truly understands the problem. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Outlook’s weak spot is that it can feel heavy and slow, especially when your inbox is large or when switching between features. Some settings are buried deeper than they need to be, and occasional sync hiccups can interrupt your flow Review collected by and hosted on G2.com.

"Outlook on Windows, solid for client emails and calendar, recall helps a lot even if its not perfect"
4.5/5
What do you like best about Microsoft Outlook?

I’ve been using it for close to eight years, and it’s just become part of my routine. It feels familiar, and I don’t have to think about it much. Day to day it’s easy enough: search is quick most of the time, and the focused inbox keeps junk out so my client threads don’t get buried. Recall has saved me a few times inside our org when I hit send too fast. It also feels more reliable lately than it used to, although it won’t help if the email has already gone to someone outside the company. For client communication it’s solid—I don’t fight the app—and security-wise, sign-in is tied to our company account, so it feels locked down and sensible.

Getting it up and running on new machines has mostly been smooth. I sign into Microsoft 365, it pulls down my mailbox and calendar quickly, company policies kick in, and I don’t need to fiddle with much. Years back we did have a couple of profile hiccups and a massive OST that got cranky; I had to reset things and rebuild the index. It took a chunk of a day, but once it was done it stayed stable. Since then, updates roll in quietly and I just keep working. I’m in Outlook basically all day, five days a week—reading, writing, scheduling—so my usage is high, and it keeps up.

Feature-wise, there’s a lot I actually use instead of just ignoring. Rules and categories help me keep client work sorted, and delay send is a lifesaver when I want a second look. Shared mailboxes make teamwork simpler, and calendar invites drop in a Teams meeting so I don’t have to think twice. Attaching files from OneDrive is clean, and it turns the attachment into something that stays updated, so versioning doesn’t bite me as much. Search across years is good, though sometimes the index gets weird and I have to rebuild it—annoying, but not a deal breaker. Integrations are strong for me: Outlook plays nice with Teams and SharePoint. A couple of add-ins like CRM were hit or miss; one made things sluggish, so I removed it and it was instantly better. Support-wise, the official help pages and community posts usually get me unstuck. It’s not perfect, but it’s enough to move forward.

Overall, I’d definitely recommend it. It’s the most complete email and calendar app I’ve used on Windows, it handles client comms without drama, recall inside the org has bailed me out more than once, and the whole setup feels secure under our company account. It’s not flawless—no app is—but for day-to-day work it does what I need and stays out of the way. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Time zones and recurring meetings can get weird. I’ve had a few double bookings because an update didn’t sync correctly to a shared calendar, or the meeting showed up late. Forwarding meeting invites to a client also isn’t always straightforward; sometimes people end up with two versions, or the attachment gets lost. The new Outlook direction versus classic adds another layer of confusion: buttons move around, some features seem to disappear, and I have to re-learn where things are, like Delay Send or Message Options. It’s fine once you settle in, but the constant changes still steal time.

Email recall is much better within the org now, but it can create a false sense of safety if you forget it won’t pull back something sent externally. I still double-check sensitive emails and often use Delay Send, because recall isn’t a magic undo. Sync on shared mailboxes can lag too; unread counts get out of sync, and it makes me think I missed a message when the cache just didn’t update. Review collected by and hosted on G2.com.

"Easy to Use and Feature-Rich—Microsoft Outlook Stays Reliable"
5/5
What do you like best about Microsoft Outlook?

Overall, I like how easy it is to use—Microsoft Outlook remains a constant for me, even with updates. I use it daily for both work and personal needs. I also enjoy the features it offers, such as delaying sends, callback messages, and being able to like or use emojis to react to messages instead of having to write a full response. I’ve also found the Copilot integration features helpful. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

Dragging files for download — I used to be able to drag and drop attachments directly from Outlook, but now I have to download them first. Review collected by and hosted on G2.com.

What do you like best about Microsoft Outlook?

I really like how Outlook brings everything together in one place emails, calendar, contacts, and tasks. The interface feels clean and easy to navigate, and I love how I can schedule meetings directly from my inbox without switching apps.

What do you dislike about Microsoft Outlook?

Sometimes Outlook can feel a bit heavy, especially when syncing large mailboxes, it slows down or freezes for a few seconds. The mobile app could also be a little faster when loading attachments or switching between accounts. Other than that, it’s generally very dependable. Review collected by and hosted on G2.com.

"All-in-one platform for email, calendar, and collaboration"
5/5
What do you like best about Microsoft Outlook?

I appreciate how Microsoft Outlook brings together all my communication, scheduling, and task management in a single platform. The interface feels intuitive and familiar, making navigation straightforward, and I like how seamlessly it syncs between desktop and mobile devices. Features like the focused inbox, robust search, and integrated calendar help me save valuable time, especially on hectic workdays. I also value its smooth integration with Teams and other Microsoft 365 apps, which streamlines collaboration and minimizes the need to constantly switch between different tools. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

While Outlook offers a lot of powerful features, I sometimes find it slow, particularly when managing large mailboxes or several accounts at once. The interface may appear somewhat cluttered to new users, and some features—such as rules and search filters—are not always straightforward to use. There are also occasional syncing issues between the desktop and mobile versions, which sometimes require me to refresh manually. Although these drawbacks are relatively minor compared to the overall benefits, they do occasionally affect my workflow. Review collected by and hosted on G2.com.

"Efficient Email Management with Helpful Features"
4.5/5
What do you like best about Microsoft Outlook?

I love how easy Microsoft Outlook is to use; the step-by-step setup process made it straightforward for me to understand and operate. The 'Out of Office' feature is fantastic because it automatically informs my contacts about my availability, especially when I'm out of state. I find immense value in the ability to organize my emails efficiently with the folder creation feature. The signature options provide a professional touch to my emails, and the ability to undo sent emails is a lifesaver when I make mistakes. Another refreshing aspect is the seamless integration with Microsoft Teams, enhancing my workflow. Overall, I'm very satisfied with the current features Outlook offers.

"Effortless Email Organization and Seamless Sync Across Devices"
5/5
What do you like best about Microsoft Outlook?

MS Outlook is very cool because it helps me keeping all the emails in order. I can make folders and stuff to sort them. And its calender, where I can plan all my appoinetments and get reminded of them, in case I forget. I can even make a to do list in it. It works best with other MS applications. And can use it over laptop, phone and tab, it is always in Sync. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Outlook?

I feel it gets slow when there are multiple emails. There are so many buttons that some times it becomes hard to find what are you looking for. The search is not up to the mark. It gives random results sometimes. The settings are little difficult to understand and tough to change the things as required. Review collected by and hosted on G2.com.
