Calendar sync with Gmail is weak and doesn't update consistently or live. Work together!

I would see my events that are liked to my outlook directly at the home page
allow outlook exchange corporate calendar to be added in android. this would allow the setting of do not disturb on the phone related to outlook calendar contacts. as it stands I get calls in meetings.
I just upgraded my phone, and on my old phone (Samsung GS5) I had a work email account thru Exchange. On my old phone I could make calendar events for my Gmail account or for my work Exchange account, and everything was on one consolidated calendar. I could open a new event in my phone's ecosystem (Android), I would choose what account to associate the the event with, fill in details, and done. Then, all events could be seen in one calendar ecosystem (Again, Android). With my new phone (Samsung GS20) it seems Exchange (via Outlook) doesn't talk to android, and it has it's own calendar ecosystem, and I can't make work events with my Exchange account in the android calendar. So, now I have to use two calendar applications, and I can't view both simultaneously. Same Exchange account, same Gmail account, new phone breaks everything.
Sync the tasks from the exchange account and To do app. Have it display in the calendar.
