Bug#993295: Calendar: Notifications deleted on reoccurring appointments

[Drexl Johannes]

Package: evolution-ews
Version: 3.38.3-1
Severity: important
X-Debbugs-Cc: johannes.drexl at nfon.com

Dear maintainer,

using multi-instances calendar entries with notifications has the 
following error:

The first instance is notifying as wished for. On dismissing the
notification, notifications are deleted on all instances, so the
following instances don't remind any longer. This is only occurring 
while using an EWS calendar; my local calendar does not display 
such behaviour. Used EWS instance is outlook.office365.com/EWS.
