Opera copied Netscape which had email three years earlier (June '97 compared to Opera's June 2000) when groupware was still a thing in the 90s. Everyone except Opera realized the bundling of email and calendar and chat and more was wrong for most folks by around 2003 and pared back following Firefox and Safari to streamlined interfaces with only the most important features and leaving everything else to extensions. Opera (and MyIE/Maxthon) doubled down on bundling features until it was an unsustainable monstrosity and when that became clear the board kicked out the founder and not long after the CTO and inventor of CSS left and the Chinese now own it so it's just another Chromium skin.
