+Date: Thu, 27 Sep 2018 10:51:05 +0200
+Subject: Collection backend schedules two 'populate' requests after going
+ online
+
+ECollectionBackend base class makes sure the 'populate' method is called
+after the backend itself goes online, thus there is no need to schedule
+it in the descendant again.

+Date: Tue, 2 Apr 2019 16:06:35 +0200
+Subject: [PATCH] M!1 - Simplify OAuth2 for outlook.office365.com server
+
+Two changes:
+1) preset default tenant to "common"
+2) do not pass 'scope' parameter in the requests, which is optional
+   and can cause errors like:
+   error:invalid_request description:AADSTS65002:
+   Consent between first party applications and resources must be
+   configured via preauthorization.
+
+Closes https://gitlab.gnome.org/GNOME/evolution-ews/merge_requests/1
