Microsoft is rolling out a new version of Outlook for Windows that will eventually replace the classic Outlook experience many have used for years. While both versions will be supported in parallel until at least 2029, Microsoft encourages users to start familiarizing themselves with the new Outlook.
So, what’s different about the new Outlook compared to classic Outlook? And what does it mean for Sendent for Outlook users? Let’s break it down.
What’s new?
Streamlined interface
You’ll first notice the new Outlook’s sleek, simplified design. Expect larger icons, more whitespace, and a cleaner look and feel that aligns with other modern Office 365 apps. While the classic Outlook layout may feel more familiar, the new interface aims to help you focus on what’s important with less distraction.
Faster performance
Under the hood, the new Outlook brings major speed and performance improvements. Reduced load times and snappier transitions between mail, calendar, contacts and tasks make it easier to fly through your workflow. This is especially noticeable if you manage multiple accounts.
Enhanced 365 integrations
The new Outlook offers tighter integration with the Microsoft 365 ecosystem. As Microsoft positions Outlook as a productivity hub, expect a more seamless experience with apps like Teams, OneDrive, and SharePoint. Classic Outlook still works with these apps, but the new Outlook makes cross-app collaboration even smoother.
Built-in security
Security and privacy see a major upgrade in the new Outlook. Stronger defenses against phishing and malware are built right in. For organizations, there are also more robust admin policy controls, like the ability to require two-factor authentication. While classic Outlook remains secure, the new Outlook takes protection to the next level.
Optimized for mobile
For those who frequently access Outlook on smartphones and tablets, the new Outlook is designed with mobile in mind. The interface adapts gracefully to smaller touchscreens for an improved on-the-go experience compared to classic Outlook’s more desktop-centric UI.
Classic features not yet in new Outlook
While the new Outlook brings many enhancements, some classic Outlook features are not yet available in the new version. According to Microsoft’s feature comparison, elements like multiple account support, full offline capabilities, and certain calendar views are still under development for the new Outlook.
Power users may also notice the absence of advanced features like Custom Forms, Quick Steps, and Search Folders in the new Outlook, at least for now. Microsoft plans to expand feature parity over time based on user feedback and priorities.
Exchange on-prem support
One important consideration for organizations using Exchange Server on-premises is that the new Outlook’s support for this configuration is currently listed as “under investigation” in Microsoft’s feature comparison.
This means that companies heavily invested in on-prem Exchange should carefully evaluate new Outlook’s compatibility with their environment before making the switch. Microsoft has stated they will provide more guidance to on-prem customers as the new Outlook evolves.
In the meantime, classic Outlook remains fully compatible with on-premises Exchange deployments, offering a stable choice for organizations not yet ready or able to move to the cloud.
Potential downsides and privacy considerations
While the new Outlook brings many improvements, there are a few potential downsides to consider. Some users may find the new interface unfamiliar and need time to adjust their workflows.
Additionally, as a more connected web-based app, the new Outlook may collect more user data than classic Outlook for features like Insights and the upcoming Microsoft Copilot. While Microsoft maintains this data is used to improve user experience and is protected under their privacy policy, organizations with strict data handling requirements should review new Outlook’s privacy settings and controls.
As with any major software transition, a thorough assessment of organizational needs, compatibility, and compliance is recommended before making the switch.
How to enable new Outlook
Microsoft will continue to support both Outlook versions until at least 2029. However, new Outlook will become the default for fresh installs going forward.
For existing classic Outlook users, the new Outlook is currently opt-in. You can try it out by simply toggling it on from the top right corner of classic Outlook. All mail, calendar events, and contacts sync over automatically.
If you’re not ready to switch, no worries. You can bounce between both experiences as Microsoft continues refining the new Outlook based on user feedback.
It’s important to note that Sendent offers two distinct add-ins for Outlook: the Sendent for Outlook (Windows Only) VSTO add-in, compatible with classic Outlook on Windows, and the Sendent for Outlook (Cross-Platform) web add-in, designed for the new Outlook experience across Windows, Mac, and web.
While Cross-Platform subscribers have access to both, ensuring a smooth transition, it’s crucial to have the appropriate add-in installed for your chosen Outlook version. If you toggle to the new Outlook without the Cross-Platform add-in in place, you may encounter interruptions in your Sendent functionality. As Microsoft rolls out the new Outlook, Sendent remains committed to supporting both versions, keeping your data privacy uncompromised throughout your journey.
How to stop or delay new Outlook
Microsoft will continue to support both Outlook versions until at least 2029. However, new Outlook will become the default for fresh installs going forward.
