[Bug 2118883] [NEW] Microsoft 365 calendar account has empty URI in GNOME Online Accounts on Ubuntu

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Description:
On Ubuntu, when adding a Microsoft 365 account via Settings → Online Accounts, the account appears in GNOME Online Accounts but GNOME Calendar cannot authenticate or sync events.

After some investigation, it seems that the Calendar backend for
Microsoft 365 accounts does not set a valid CalDAV/EWS Uri, while Google
accounts do.

Steps to Reproduce
Open Settings → Online Accounts and add:

A Google account

A Microsoft 365 account

Verify the calendar backend with:

gdbus introspect --session \
  --dest org.gnome.OnlineAccounts \
  --object-path /org/gnome/OnlineAccounts \
  --recurse
Compare the Calendar interface for both accounts.

Expected Behavior
Both accounts should have a valid Uri in the org.gnome.OnlineAccounts.Calendar interface.

Microsoft 365 should expose a proper calendar endpoint (CalDAV or EWS),
similar to Google.

Actual Behavior
Google account shows a proper Uri, for example:

readonly s Uri = 'https://apidata.googleusercontent.com/caldav/v2/...'
Microsoft 365 account shows:

readonly s Uri = ''
GNOME Calendar fails with:

Failed to authenticate: Cannot find a corresponding account in org.gnome.OnlineAccounts
Environment
Ubuntu version:  25.04

GNOME version:  48

gnome-online-accounts version: Package: gnome-online-accounts
Version: 3.54.1-1


evolution-ews package installed: yes

Workarounds Tried
Installed evolution, evolution-data-server, and evolution-ews

Removed and re-added Microsoft 365 account

Restarted services:

killall goa-daemon evolution-calendar-factory
/usr/libexec/goa-daemon &
/usr/libexec/evolution-calendar-factory &
Still, the Uri remains empty and calendar sync does not work.

Impact
Microsoft 365 accounts cannot sync calendar events in GNOME Calendar.

Likely a bug in gnome-online-accounts or its Microsoft 365 calendar
integration.

Suggested Fix
Investigate why the Microsoft 365 calendar backend fails to populate the Uri.

Ensure that evolution-ews or appropriate connector is automatically
used.

Align behavior with Google accounts where Uri is properly set.
