Before this commit, when a user was invited to an event from an account outside Outlook (e.g. Google account), accepting the invitation in Outlook Calendar didn't send the 'accept' status to Odoo Calendar, and vice-versa. This problem was also happening with recurrent events accepted in Outlook, the events weren't being accepted in Odoo Calendar correctly. Additionaly, when 2+ attendees from Odoo were synced (having the organizer as an external user), only the last user to sync the event was able to answer it in Odoo due to its outdated 'microsoft_id'.
After this commit, both ways are fixed: accepting an event in Outlook Calendar or Odoo Calendar notifies the other calendar correctly. For recurrent events, accepting them in Outlook Calendar also updates the events status to 'accept' in Odoo Calendar (reminder: due to a limitation in Outlook Calendar synchronization, when the synchronization is active recurrent events acceptance can only be done through Outlook). In addition, all attendees from Odoo can now answer an event that came from external organizers.
