Outlook Fonts change once you compose a new email or reply to an email

Issue:

 

Everytime once you compose a new email or reply to an email, Your Outlook's new message window shows very big or timy letters.

 

Cause:

 

If your font looks smaller or bigger than the actually configured font size, your zooming factor has been set above or below 100%.

 

Resolutions:

 

You can change it back in the following way:

 

Outlook 2010
When composing click on the Zoom button on the Home tab.

 

Outlook 2007

When composing go to the Format Text tab and click on the Zoom button.

 

 

Previous versions of Outlook
You can only zoom when you have Word set as the email editor. The Zoom function can be found in the View menu.

 

Note:
The change in the zoom factor probably was caused by holding the CTRL button while scrolling. This is an alternative method to change the zoom factor.
