Email Template Not Showing Up Properly Upon Receiving in Outlook
|Knowledge Article Number||000006221|
Email templates sent from Salesforce do not show up properly in Outlook or other email clients. For example the images within templates look smaller upon receiving in Outlook, images are missing, and etc
First of all you need to know that Salesforce has no control over this. A message that you create and send in Salesforce or even any email client, may not look the same in the recipient's e-mail program.
If the images show up properly on the other email clients or while viewing in a browser it indicates that Salesforce has processed the images properly and it is Outlook which seems to be the cause of this issue. There is no issue with regard to any Salesforce email template setting, but rather some changes needed to be done on the Outlook side.
While it is true that Outlook is a very popular email client, it is beyond our control how Outlook is designed to handle/deliver email. Similar to the limitations of fonts or colors in internet explorer or any other browser where it cannot be influenced by Salesforce even though Salesforce has a number of users that use Internet Explorer as their primary browser.
