for Office 365
In Office 365 preview messages setting, when the option "Write a message in new window" is selected, the webpage on Secure Browser will not be displayed properly. Why is that so?
HDE Secure Browser has a mechanism to prevent pop-up, contents blocker, and similar functions. When the webpage is being redirected, the browser will not open a new tab and attempt to redirect to the new page within 1 tab instead.
Therefore, any webpage components that utilize pop-up function will not be displayed properly.
