Post by Chris Dear All, couldn't accept appointment in Lightning. The dialog in Lightning looks different with Open-Xchange. I can accept the meeting in the advanced menu / status, but it isn't synced to SOGo. Accepting in the webinterface and CalDAV works fine. Is this a known issue?
The SOGo connector was installed of course. It's working with Open-Xchange, not with SOGo. It's the most recent Thunderbird and Lightning version. Reinstalling the plugins, deleting and creating the calendar again didn't help.
