        Hi,
evolution-ews itself didn't receive many changes, as can be seen here:
https://git.gnome.org/browse/evolution-ews/tree/NEWS?h=gnome-3-26

The change in 3.26.3 truly touches the calendar part [1], though it was
mainly meant to avoid runtime warnings and or crashes in certain
situations.

The bug us currently stuck, because I also was not able to reproduce
the issue here. I would expect that Office365 server will behave pretty
close to your Exchange instance, because they may use the latest
version (that's only my expectation, for which I do not have any
proof).

Note of the comment in the middle of the [1], about:

   Workaround Exchange 2016 error, which returns invalid iCalendar
   object (without 'END:VCALENDAR')

Maybe they broke it in some other way. I'm going to follow on your bug
report with an idea.

        Thanks and bye,
        Milan
