Keep within the same tab/window.
In the old outlook web interface, switching between mail and calendar kept everything in the same tab or window. In the new outlook web interface, everytime I switch between mail and calendar it opens a new tab. This is really annoying.
Opening a different section/part of Outlook no longer opens in a new browser tab. Used to be, if you were in e.g. Mail and clicked on Calendar, the latter would open in a new tab, keeping Mail in its own tab. This is very handy. Now, everything just changes within the same tab. This is impractical for overview purposes. There should be an option to turn new browser tabs on again, like it was previously.
More interesting is that when You switch to old version of calendar and than go back to outlook, it switch to on old version of outlook :)
This is how this functioned until today for me, now suddenly if I go to calendar, it changes the tab from Mail to Calendar as it should, but when I try to click back to Mail, it keeps generating a new window for Mail. I want it to switch in the same tab as it was doing until today.

This looks similar to https://outlook.uservoice.com/forums/907141-the-new-outlook-on-the-web-office-365/suggestions/36708415-do-not-open-calendar-contacts-or-tasks-in-a-new-w which is not fixed, even though it says it is.
Why does it launch a new browser window or tab for navigation. I select the calendar, a new window opens, I select mail, a new window opens
