Microsoft Outlook has remained one of the world’s most trusted email and productivity platforms for years, serving professionals, businesses, students, and personal users alike. It is far more than just an email client, offering integrated calendars, contacts, tasks, notes, meetings, and Microsoft 365 collaboration features. Because so many people use Outlook daily for communication and organization, even small interface changes can significantly impact productivity.
One of the most noticeable and often frustrating updates in newer versions of Microsoft Outlook has been the relocation of the navigation toolbar from its classic bottom position to a vertical sidebar on the left side of the screen. For long-time Outlook users, this shift can feel disruptive, unfamiliar, and inefficient. The side toolbar takes up horizontal workspace, changes muscle memory, and can slow down navigation for those accustomed to quickly switching between Mail, Calendar, People, and Tasks from the bottom bar.
While Microsoft introduced this redesign to align Outlook with other Microsoft 365 apps such as Teams and OneDrive, many users strongly prefer the traditional layout. Fortunately, depending on your Outlook version, there are ways to move the toolbar back to the bottom or at least restore a more familiar navigation experience.
This detailed guide explains why Outlook’s toolbar moved, how to move Microsoft Outlook’s toolbar from side to bottom, version-specific methods, common issues, and additional interface customization tips to improve your workflow.
Why Microsoft Outlook Moved the Toolbar to the Side
Microsoft’s redesign was largely part of a broader strategy to unify its Office ecosystem. By moving the navigation toolbar to the left, Outlook gained a more app-centric structure similar to other Microsoft 365 applications.
The goals included:
- Better consistency across Microsoft apps
- Easier switching between Outlook, Teams, and OneDrive
- Improved vertical integration
- Expanded collaboration features
- Space for future feature additions
However, many users found drawbacks, including reduced horizontal reading space, especially on smaller monitors or laptops. Email lists, reading panes, and calendar views often feel more cramped when the side toolbar is active.
For users who primarily rely on traditional Outlook functions rather than broader Microsoft 365 integration, the bottom toolbar often remains more practical.
Which Outlook Versions Allow Toolbar Changes?
The ability to move the toolbar depends heavily on which Outlook version you are using.
Common versions include:
- Outlook for Microsoft 365
- Outlook 2021
- Outlook 2019
- Outlook 2016
- New Outlook preview versions
- Outlook Web App
- Outlook on Mac
Some versions allow easy restoration of the bottom toolbar, while newer builds may have more limited customization.
Method 1: Disable “Coming Soon” or New Outlook Features
For many users, the toolbar shift originally arrived through Microsoft’s “Coming Soon” or updated interface toggle.
Steps:
- Open Outlook
- Look for the “Try the new Outlook” toggle or “Coming Soon” switch in the upper-right corner
- Turn it off
- Restart Outlook
Once disabled, Outlook often returns to its traditional layout with the bottom toolbar restored.
Benefits:
- Quickest solution
- Restores familiar interface
- Minimal configuration
- Ideal for classic Outlook users
Important note:
Microsoft may phase out this option in future versions.
Method 2: Disable the Navigation Bar Through Outlook Options
In some desktop versions, Outlook’s interface can be partially adjusted through settings.
Steps:
- Open Outlook
- Click File
- Select Options
- Go to Advanced
- Look for Outlook Panes or Navigation settings
Depending on your version, adjusting these settings may restore or simplify the navigation layout.
This method may help:
- Reduce sidebar prominence
- Customize pane arrangement
- Improve usability
Method 3: Use Windows Registry Editor
For advanced users, Registry modifications can often restore the classic bottom toolbar in supported Outlook versions.
Steps:
- Press Windows + R
- Type
regedit - Press Enter
Navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides
Create a new String Value:
Microsoft.Office.Outlook.Hub.HubBar
Set value to:
false
Restart Outlook
This registry adjustment can disable the newer sidebar in some builds.
Advantages:
- Effective for many users
- More persistent
- Restores classic interface
Warning:
Registry editing should be done carefully. Incorrect changes can affect system behavior.
Method 4: Disable Shared Experiences or Office Experiments
Microsoft often rolls out interface changes through experimentation frameworks.
Possible steps:
- Open Office Account settings
- Disable connected experiences where applicable
- Limit preview features
- Opt out of Insider builds
This may reduce forced UI experiments in some cases.
Method 5: Roll Back Office Updates
If a recent update introduced the sidebar, reverting to an earlier Office version may help.
Steps:
- Open Command Prompt as administrator
- Use Office deployment rollback commands
- Restore previous stable version
Best for:
- Enterprise users
- IT-managed environments
- Users requiring consistent workflows
Downsides:
- Temporary solution
- May lose newer security updates
Method 6: Customize Navigation Pane Width
If moving the toolbar fully is unavailable, reducing sidebar width can reclaim screen space.
Steps:
- Hover over pane border
- Drag to resize
- Minimize where possible
Benefits:
- Better reading area
- Less visual intrusion
- Improved laptop usability
While not identical to the bottom bar, it can improve comfort.
Outlook Web App Limitations
Outlook on the web generally follows Microsoft’s newer interface standards more strictly.
In web versions:
- Sidebar customization is limited
- Full bottom bar restoration may not be possible
- Interface is more standardized
Users seeking maximum classic customization may prefer desktop Outlook.
Outlook for Mac Differences
Mac users may experience slightly different navigation options.
Possible adjustments include:
- Ribbon customization
- Sidebar minimization
- Legacy Outlook toggle
- View preferences
Microsoft’s Mac versions often differ from Windows builds in feature rollout.

Benefits of Restoring the Bottom Toolbar
For many users, the classic bottom navigation remains superior.
Advantages include:

Final Thoughts
Microsoft Outlook’s shift from a bottom navigation toolbar to a left-side sidebar has been one of the more divisive interface changes for long-time users. While Microsoft’s goal was broader ecosystem integration and modern design consistency, many users still prefer the traditional bottom layout for its efficiency, familiarity, and better screen space management.
Fortunately, depending on your Outlook version, there are several ways to move Microsoft Outlook’s toolbar from side to bottom or at least reduce the impact of the newer sidebar. Methods such as disabling preview features, adjusting settings, editing the Windows Registry, or using classic Outlook versions can help restore a more comfortable workflow.
For professionals who spend hours each day managing email, calendars, and tasks, even small usability improvements can make a major difference. By customizing Outlook to match your preferred work style, you can regain productivity, reduce frustration, and create a more efficient communication environment.
