I have just installed Office 365 2016 for Mac and everything seems to work fine except...
...When I try to start Outlook I get a message that I shall upgrade the Outlook Database. When I klick the upgrade button I get a message that It is not possible to upgrade the database with Outlook. (se printscreens).
What to do?
I Had the same problem after countless hours of research i found a fix that worked for me.

To summarize we have to create a new profile and setup your exchange account:
1. Quit Outlook application.
2. Go to ‘Applications’ > right click on Outlook app > Then click on ‘Show Package Contents’ .
3. Expand ‘Contents > click on SharedSupport > Open ‘Outlook Profile Manager.app.
4.Click on ‘+’ sign to create new profile > After naming your profile Click the 'gear' icon and set the newly created profile as the default profile.
5. Open outlook.
