[Solved] Evolution EWS Setup Fails

[RavenLunatic]

Hi everyone,

I’m trying to set up a EWS account in Evolution on Ubuntu Noble, and I’ve hit a wall that I can’t get past, and AI is sending me round in circles.

My system

• Ubuntu Noble

• Evolution 3.52

• evolution‑ews 3.52.0‑1build1 (confirmed installed)


The problem

When I try to add my Microsoft 365 account, Evolution never shows the proper EWS setup screen. Specifically:

• Autodiscovery does not appear, and there is no Cancel button

• I get the screen where you can choose Exchange Web Services

• I never see the Authentication dropdown

• OAuth2 never appears

• The Microsoft login window never opens

• If I Check for supported types… no supported types available



The result if I manually override Oauth2 is that the account gets added but has no mail, no calendar, no contacts, because it never authenticated. I now know manual overrides are not allowed.


What I’ve already tried

• Confirmed evolution-ews is installed

• Disabled old Microsoft 365 account

• Cleared Evolution caches ~/.cache/evolution and ~/.config/evolution/sources

• Restarted Evolution with evolution –-force-shutdown

• Ensured I’m using Evolution → Edit → Accounts → Add → Mail Account (not GNOME Online Accounts)

• Widened the setup window in case OAuth2 was hidden

• Reinstalled Evolution and evolution‑ews

• Rebooted the system


What I expect to see (but don’t)

• Autodiscovery with a Cancel button

• The Authentication dropdown with OAuth2

• The Microsoft login window



Why is Evolution skipping the EWS setup flow entirely, and how can I force it to show the OAuth2 authentication option so Microsoft 365 can authenticate properly?

Any guidance would be hugely appreciated.

My investigations have reveled the EWS is being discontinued in October this year and I should use Microsoft Graph (Microsoft 365) instead.
