It can be slow at times, especially with large mailboxes, and the interface feels cluttered. Some features, like search and rules, aren’t always intuitive or consistent across desktop and mobile. Review collected by and hosted on G2.com.

I don't love the functionality and the user experience. It works well with the rest of the Microsoft Office Suite, but I really miss when we used Google Workspace. It was more intuitive, less clunky. Review collected by and hosted on G2.com.

It’s really easy to use, and it helps organize emails efficiently, making tasks easier to complete. However, there was a time when it automatically logged me out and required a Duo authentication process through the app before I could log back in. Review collected by and hosted on G2.com.

Microsoft Outlook is a powerful and reliable communication tool. It helps me manage emails, calendars, meetings, contacts, and tasks all in one place. As a part of Microsoft 365, outlook works smoothly with other Microsoft tools and offers strong security, making it easy to stay organized and connected at work.

Microsoft Outlook has many useful features, but sometimes it feels overwhelming because of number of options available. The interface can be bit complex for new users, and performance may slow down when handling large volumes of emails. Review collected by and hosted on G2.com.

I use Outlook every day for business and when I have to switch to Gmail for personal use I am always dissapointed because it does not have the same features I am used to with Outlook. I think the best feature is the use of search for previous emails that I've ever sent or received. Review collected by and hosted on G2.com.

There isn't really anything I dislike about Outlook. It's the most advanced email tool I've used. And now that Microsoft has integrated Copilot, it's even better. Review collected by and hosted on G2.com.

Microsoft continues to stand out for its tight integration with other MS products and the broader MS 365 ecosystem. For end users, the experience feels familiar and consistent across devices, and it becomes highly productive once everything is configured. Email, calendar, Teams meetings, contacts, shared mailboxes, and file collaboration all come together in a single interface, which helps reduce context switching and makes day-to-day workflows more efficient.

From an administrator’s perspective, Outlook paired with Exchange Online provides solid centralized management. The Microsoft 365 admin tools let admins handle mail flow, retention policies, permissions, compliance, and security controls through web-based consoles, keeping key settings and oversight in one place.

Onboarding new users is also fairly straightforward. Auto-discovery, cloud synchronization, profile portability, and cross-device support help minimize setup friction for people moving between desktop, mobile, and web. Overall, Outlook remains powerful enough for enterprise governance while still being approachable for non-technical users. Review collected by and hosted on G2.com.

The biggest challenge with Outlook today is the inconsistency between the classic Outlook client and the newer Outlook experience. Some of our users report performance issues, a sluggish UI, and incomplete feature parity in the new client.

For our admin team, management workflows also feel fragmented across multiple admin portals. Security settings, Exchange settings, compliance controls, and identity configurations are spread across different interfaces, which slows down day-to-day work—especially with some of the newer admin center designs.

On top of that, most of the team (myself included) feels Microsoft is pushing Copilot integration too aggressively before the overall experience is fully mature. The intrusive UI elements and AI scenarios that don’t add much value are irritating for many of us. Review collected by and hosted on G2.com.

It helps me use folders to categorize different clients’ emails, and I’m also able to read previous messages related to the same client using its unique features. Review collected by and hosted on G2.com.

Sometimes, due to a severe issue, Outlook becomes slow. Also, I sometimes schedule emails, but they are sent to the client only when the PC is on. If the PC is off, the email still remains in the Outbox. Review collected by and hosted on G2.com.

Microsoft Outlook is helpful because it combines email, calendar, contacts, tasks, and scheduling into one application, making it easier to stay organized and productive. Review collected by and hosted on G2.com.
