Microsoft Outlook offers a range of features to enhance your email messages, and one such feature is the ability to include images in your emails. You can attach an image file, or embed it within the email body. Each method has its advantages and drawbacks.

Inserting an image into the email body allows for direct viewing, making it convenient to see both the email content and the image simultaneously on the same screen. It is particularly useful when you need to explain a scenario, provide a screenshot, or illustrate examples with images. In contrast, when you attach an image, it can't be viewed directly within the email and must be opened, saved, or downloaded separately. This approach is more suitable when multiple images are attached, or recipients require the image files for later use.

Regardless of the method you choose to send your email, resizing your images may be necessary. For inserted images, you might want to crop them to remove unnecessary elements or resize them to better align with the email's content. When dealing with image attachments, resizing can be beneficial in reducing the image size, enabling you to include more image files in a single email.

Well, there are multiple ways to resize images in Outlook email.

We’ll discuss each of the above methods in a more detailed manner.

Note: Many organizations and email service providers, such as Gmail, Yahoo, and Exchange, have limitations on sending large files through their email systems. When attempting to send a large image file as an attachment, users often receive an alert stating, 'Your file is too large to send.' To address this situation, resizing the image file within Outlook mail can be a viable solution.
