We've had notification emails which include links throughout the email such as "<a href="#action">Jump to action section</>" and then we include "<a id="action" name="action"></a>" in that section of the email. This works in all email clients we've used for years, including Outlook 2010.
However, in the Office 365 web portal, sometimes, it converts the href anchor tags to "<a href="#x_action">", and remove the section "<a id="action" name="action"></a>". The achor cannot work in the scene.
Are there any document about pre-process rules for html in email or the logic behind OWA email rendering? How can I fix this issue?
