I’m not facing an issue with the Kopano Core server - the issue is with Kopano WebApp. The server is running on Version (8.7.25.0-2) - but that does not fixed the issue on the server where the WebApp is running.
Feel free to see more details in my other post:
Anyway - but let’s assume it would be something on the Server where Kopano Core is installed - what is it that can do to get it fixed?
