Good afternoon.

I will describe the problem step by step. There is a mail server. It has a web version of mail (SOGo). Created an account for the meeting room. Created a shared calendar and signed mail users with rights to create entries in this calendar. In mail clients connected calendars over the network with user credentials. When creating an event in the calendar, added participants. Participants receive an email with an invitation. Immediately, when the email arrives to the participant, there are buttons to accept, but as soon as the event is synchronised and added to the calendar, the buttons disappear. Why? An error occurs when clicking on the refresh button. Why? How to set up a shared calendar correctly? Is there any instruction?

I always find it useful. I have one problem. I usually only display [Attachments][Subject][Recipient][Date], but the default displays [Thread][Star], etc., and I have to edit them each time. Is it possible to create a [User default] by changing the settings? Thank you.

The theme keeps resetting randomly to "dark" - although it shows that the "light" theme is enabled - it still switches to "dark", i.e. the interface is the dark mode. I then have to Disable and Enable the Light Mode for it to be Light mode again. But, then even within a few minutes, while I might be doing something else - when I go to Thunderbird, it has switched to Dark mode again .... This is FRUSTRATING.
