Hi *,

since evolution-ews-3.26.3 handling of recurring appointments got even
worse.

Before, I had problems when modifying a single appointment in a series
from evolution calendar gui. This lead to a duplicate entry:
https://bugzilla.gnome.org/show_bug.cgi?id=789899.

Since 2.6.3 *every* modification of a recurring appointment leads to a
duplicate entry, even modifications for meeting requests sent by the
original organizator. The same entry shows correctly in Outlook -
modified and without a bad brother 8-<
Even worse: Deleting the duplicate entry in evolution removes both
entries in evolution, the correct entry in outlook and sends out a
decline message to the organizator.

With this behaviour evo has become completely useless for me, because I
need calendar and meetings requests more than even email.

Does anyone have any hint?

EWS is talking to an Exchange Server 2016 CU5.

TIA.
Bye.
Michael.

I am using 3.26.4, and we do not use Exchange, but office365 rather.  We also have a corporate WebEx server at my disposal to test.  I just created recurring meetings on both systems, and edited them several times.  Evo Calendar correctly updated the meeting every time and no duplicates occurred.

Sounds like your Exchange Admin might have some settings causing this more than likely.  I have been using evo for a very long time and have never witnessed the symptoms you are seeing, and I am a very heavy calendar/meeting user.

I just went through all of the tick boxes, and while I am not positive, none of the options under preferences seem like they could cause this either.
