We have a customer who is using kerio connect with a outlook 2016 plugin. I am able to invite this customer to a
series and process his response without problems. But when the customer later decides that her cannot attend a specific
event from the series, he declines participation. I then receive his update via mail and also i am shown the "Update Status"
button from within SOGo Webinterface, but clicking on it does not update this specific event.
After clicking that "Update Status" button and changing the module to calendar and back to mail, the button is gone.
So i assume SOGo processed that somehow.
I will attach the original series and the response privately

I dont't know if SOGo could do something here, but in regards to better integration i felt it was correct to post here
