The webmail is dead, long life the webmail

Well in fact, it's not called anymore the "webmail".

You can now have a rich content editor , and you are nearly able to do as much as you want to do in your classic Outlook.

To access it:

When you are in any instance of office 365 (SharePoint, teams, word online...), click on the Waffle icon and select "Outlook"

OR

Navigate to "https://outlook.office.com/"

if not yet connected, type your complete email address and password.

Open

You have now access to a whole new world of Outlook
