How to fix an email screen that's too big.

Hi Diane Ball, 

I understand how inconvenient it can be when the email window becomes too large and the Send button is no longer visible, especially when there is no scroll bar to move around the screen.  

To better understand the situation, could you please share a bit more information? 

• Which email app are you using? For example: new Outlook for Windows, Mail app, Outlook desktop, or email in a browser such as Edge/Chrome? 
• Does the screen look too large only in the email window, or does the same issue happen in other apps too? 
• Are you using a laptop screen only, or an external monitor? 
• Did this start after changing any display, zoom, or accessibility settings? 

In the meantime, please try the steps below: 

1. Reset the zoom level 

• If you are using email in a browser or an app window, press: Ctrl + 0 
• This resets the zoom back to 100%. 
• If you are using Microsoft Edge or Chrome, click the three dots menu in the top-right corner and check that Zoom is set to 100%. 

2. Check Windows display scale and resolution 

• Right-click an empty area on the desktop. 
• Select Display settings. 
• Under Display resolution, choose the option marked Recommended. 
• Close and reopen the email app. 

3. Turn off Magnifier if it is enabled 

• Please press Windows key + Esc 
• This turns off Magnifier if it is currently active. 
• You can check it manually here: Settings > Accessibility > Magnifier 
• Make sure Magnifier is turned off. 

4. Maximize or reposition the email window 

• Try pressing Windows key + Up Arrow 
• This maximizes the current window. 
• If the window seems positioned partly off-screen, try click the email window once. 
• Press Alt + Space 
• Select Move. 
• Use the arrow keys to move the window back into view. 
• Press Enter when the window is in the correct position. 

5. Repair the email app 

• Open Settings > Go to Apps > Installed apps. 
• Find the email app you are using, such as Outlook or Mail and Calendar. 
• Select the three dots next to it. 
• Choose Advanced options. 
• Select Repair. 
• After the repair finishes, reopen the email app and check whether the Send button appears normally. 

While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.

Increase overall text/app scaling so email windows fit better and stay usable on Windows 11.

1. Make text bigger (less intrusive change)
   1. Press Windows logo key + U or select Start > Settings > Accessibility.
   2. Select Text size.
   3. Drag the Text size slider slightly to the right to increase the sample text.
   4. Select Apply so Windows scales up all text. This helps make controls like the Send button easier to see without needing to zoom the email window itself.
2. Make apps and email windows scale better
   1. Press Windows logo key + I or select Start > Settings.
   2. Select Display.
   3. Under Scale & layout, open the Scale menu and choose a recommended value (for example, 125%). This resizes apps and windows so they fit the screen more consistently and reduces cases where parts of a window (like the Send button) are off‑screen.

If using the Windows 10 Mail app specifically and it appears too large when zoomed with Magnifier, open the message in a separate window and maximize it so Magnifier’s full‑screen view shows the whole compose area:

1. In Mail, select a message or New mail so the reading pane opens.
2. Select Open message in a new window.
3. Select Maximize in the top‑right corner of that window.

This layout works better with Magnifier and helps keep all controls visible.
