Scenario
You notice that although an image in your signature appears correct in an email, when you reply or forward an email the image appears much larger than it should.
For example:
Normal image
Enlarged image after forwarding or replying
Reason
This occurs when you resize an uploaded image in the Signature Designer. Some email clients automatically revert the image back to the original file size.
Resolution
To prevent this issue, images used within your signature design must be uploaded at your desired final size - for example, if your image file is 1000px by 1000px but you want it to appear at 100px by 100px in your signature template, you must upload a 100px by 100px version of the image file.

To check your image dimensions:
- Right-click on your image file and select Properties (Windows devices) or Get info (Mac devices).
- Open the Details tab (Windows) or More info (Mac). The image size in pixels is listed in Dimensions.
- In the Signature Designer, open your signature and select the image. Expand the Size menu in the Properties pane. The values under Width and Height are the image size in pixels.
- If the dimensions in your signature template do not match the dimensions of the original image file, reupload an image with matching pixel values.
Tip! You can use most image editing programs to resize an image. For example, to change the pixel dimensions of an image in MS Paint, select Resize from the Home ribbon and enter your new width and height values.
