Odoo calendar <-> outlook calendar sync

Hello,
We have a customer using native odoo synchronization between outlook calendar
and odoo calendar.

But since 2 month, the following warning has be added to the odoo documentation
<https://www.odoo.com/documentation/15.0/applications/general/calendars/outlook/outlook_calendar.html?highlight=outlook>
      Warning

      Odoo highly recommends testing the Outlook calendar synchronization
      on a test database and a test email address (that is not used for
      any other purpose) before attempting to sync the desired Outlook
      Calendar with the user’s production database.
      If the user has any past, present, or future events on their Odoo
      calendar before syncing their Outlook calendar, Outlook will treat
      the events pulled from Odoo’s calendar during the sync as new
      events, causing an email notification to be sent from Outlook to all
      the event attendees.
      To avoid unwanted emails being sent to all past, present, and future
      event attendees, the user must add the events from the Odoo calendar
      to the Outlook calendar before the first ever sync, delete the
      events from Odoo, and then start the sync.
      Even after synchronizing the Odoo Calendar with the Outlook
      calendar, Outlook will still send a notification to all event
      participants every time an event is edited (created, deleted,
      unarchived, or event date/time changed), with no exceptions. This is
      a limitation that cannot be fixed from Odoo’s side.
      After one user syncs their Outlook calendar to the Odoo database,
      unwanted email notifications are unavoidable because the first
      synchronized user’s events will be in the Odoo Calendar. If the Odoo
      database is shared amongst multiple users, and another user wants to
      sync their Outlook calendar with Odoo Calendar, Outlook will again
      pull the existing Odoo Calendar events during the sync and treat
      them as new events, causing Outlook to send email invitations to all
      event attendees.

      In summary, once a user synchronizes their Outlook calendar with the
      Odoo calendar:
          Creating an event in Odoo causes Outlook to send an invitation
          to all event attendees.
          Deleting an event in Odoo causes Outlook to send a cancellation
          to all event attendees.
          Unarchiving an event in Odoo causes Outlook to send an
          invitation to all event attendees.
          Archiving an event in Odoo causes Outlook to send a cancellation
          to all event attendees.
          Adding a contact to an event causes Outlook to send an
          invitation to all event attendees.
          Removing a contact from an event causes Outlook to send a
          cancellation to all event attendees.

And indeed, the synchronization has became unusable because of all the
invitations sent to all event attendees in outlook.

Odoo doesn't seem to address the problem, do you know any module that would work
properly to sync the calendars?

Regards
Simon
