I am migrating my info to outlook from the modern mail, calendar, and people apps, and I can't help but wonder why two separate software exist: The modern apps all run through outlook, yet they also have features that don't exist in the desktop version of outlook. For example, contacts do not sync with the outlook servers in the desktop app: Contacts must be imported. Also, they don't even sync with each other. If I delete mail in the modern app, idk why it doesn't get deleted in the desktop version. Is there evidence of a merger in Windows 10? Right now I'm not really understanding the point of having both of these Outlook "platforms".
