Calendar reminder for extern calendar not working

i am not be able to close the reminder of an external calendar (with no write access). All calendar events have the same standard reminder. The alarm popup comes up again and again. Whats to do? Any idea?

is this a CalDAV calendar?
Is there any message in the Tools>Operations>Error window?
What version of eM Client are you currently running? Check the Help>About section for exact version number.


Im using V. 7.0.26482.0
it is a link to an gmail calendar, this gmail calendar is linked to another external ics-calendar. Perhaps i should test the (new) direct link to an internet calendar
i see no error in the log

the error / reminder was 30 minutes ago, now it has been correctly synchronised… !?
