Hi Anne Brown,
When the Windows 11 taskbar overlaps Outlook content, such as new email tabs or the bottom portion of the window, it’s usually related to how the taskbar or display scaling is currently configured.
In addition to Q&A Assist's answer, here are some extra adjusting steps that you can follow to restore the correct layout:
1, Disable taskbar auto‑hide
- Right‑click the taskbar > Taskbar settings
- Expand Taskbar behaviors
- Turn Automatically hide the taskbar Off
2, Check display scaling
- Go to Settings > System > Display
- Set Scale to 100% and sign out/in to refresh the display
3, Refresh the window layout
- Resize the Outlook window manually, or
- Press Windows + Left Arrow, then Windows + Right Arrow to re‑snap the window
Please also confirm updates are installed
- Open Settings > Windows Update and check for updates
- Ensure Outlook is fully up to date
These steps help Windows recalculate the usable screen space so Outlook can display all content correctly.
