Hello,
Thank you for posting in Q&A forum.
If you use the image in your signature, then you can resize the image back to its original dimensions by changing the pixel values in the signature template.
To locate the signature template, hold the CTRL button when pressing the Signatures… button in Outlook’s Options dialog. This will open the Signatures folder where you’ll find the <signature name>.html file. Open this file in Notepad and search for <img>
tag. You can now change the width and height values to the exact pixel values of the original image.
Quickly open the folder by holding CTRL when clicking the Signatures… button.
Best regards,
Jill Zhou
