	Hi,
for me, "O365" is ambiguous. The evolution-ews can let you connect to
the office365.com servers by two means at the moment, it's "Exchange
Web Services" and "Microsoft 365" server types in the mail account
Properties->Receiving Email tab.

The Flathub.org does not provide apps for specific distributions. The
users can install "flatpak" on their systems and then they can use
Flatpak apps, provided for example by the Flathub.org site. You can
click through some buttons to get to instructions how to do it from the
Evolution page on their site:
https://flathub.org/apps/org.gnome.Evolution
like when you click the blue "Install" button there.

It depends. I do not use Ubuntu, I think they prefer snap over flatpak,
thus to be able to install flatpaks in the GUI you'd need to install
additional packages. I think if the App Center is gnome-software under
the hood, then they package it as gnome-software-flatpak package, but
again, I do not use Ubuntu, I do not know whether this is correct or
not. The Flathub.org site provides instructions how to enable Flathub
repositories and how to install apps from the command line, which are
just copy&paste thing, thus very simple to follow the steps there.

> How I can uninstall the old Evolution with all the user data

The data cannot be uninstalled, it is your data, not apps (sort of) ;)
You do not need to remove them though, neither uninstall the package
version of the Evolution, they can coexist. You can see in the
Help->About which version of Evolution you are running, while with the
Flatpak installed the desktop (like GNOME Shell) prefers the Flatpak
version over the packaged version.

A proper way to remove the data would be to open Evolution and remove
all user account in Edit->Preferences->Mail Accounts and then in
Edit->Accounts the custom books, calendars,... basically everything the
GUI will let you delete. To remove really everything check where the
evolution(-data-server) stores its data and move away those directories
with 'evolution' in their name:
https://gnome.pages.gitlab.gnome.org/evolution/help/data-storage.html
Then restart the machine, because some background processes could use
those files while you move them away. As always, be careful, to not
remove anything important (like some mails only under On This Computer
or such).
