Hi everybody!

I have the problem of having "endless" (a view hundred) shared calendars in SOGo.
When we try to delete one entry, another entries are created with leaving the old one.

What I've found is, this is a bug maybe in the mac calendar app.

So far so good.

I tried many things and nothing worked. So I endet up in editing the SOGo mysql database directly.
But when I edit the entry in the table "sogo_user_profile" column c_settings, the complete old entry is restored when the user logs in per SOGo-webinterface.

Then the hundreds of shared calendars are back again.

Any hint ?
