E-mail notification in Calendar App doesn't work (V10.2.1 )

Steps to reproduce

  1. Open Calendar App via Browser
  2. Create a new Calendar Event
  3. Add an e-mail recipient under “Attendees”
  4. Add a Reminder of type “Email” with e.g. “15 minutes before”

Expected behaviour

I would expect an email to be send to the previously added recipient 15 minutes before the event starts

Actual behaviour

The only email that’s been send is the actual invitation, but no reminder email.

Server configuration

Linux raspberrypi 4.19.57-v7+

Web server:
Apache/2.4.25 (Raspbian)


PHP version:

ownCloud version: (see ownCloud admin page)
V 10.2.1

Updated from an older ownCloud or fresh install:
Updated from 10.0 to 10.2.1

Where did you install ownCloud from:
don’t get that question

UPDATE 23rd July 2019:
A reminder mail is send 30 minutes before the event when I choose “1 hour before the event starts” => very strange. If I choose any other time e.g. 12 hours (“Relative”) or at e.g. 5 p.m. (“Absolute”) no reminder at all is send. I also checked whether the GUI language setting (German vs. English) might effect this behavior but this is not the case.

UPDATE 24rd July 2019:
Regardless of the choosen time to be informed prior to the event it’s always 30 minutes prior to the event that I get an email notification. Seems to be a bug…
Thanks for confirming my assumption


it seems there are no user responses since a few days. Maybe you need to create a bugreport to the ownCloud developers in this case?
