i forgot the attachement...

Thunderbird is maintaining three separate and distinct calendars. For all it knows one is yours, the other is the Managing directors and the third is a mistake you once made and never corrected.

So if you have appointments in Googles calendar they will show only in it. Thunderbird makes no attempt to integrate the calendars, only delineate the events you have added in the month view with a colour for each calendar.

While I do not speak slovak, I am fairly sure that the word zaneprazdneny that appears at the bottom of the window when you are adding these appointment means Busy. So it is your choice to go ahead and double book yourself.

hi matt, first of all, thank you for your answer. all 3 calendars are mine, im testing the functionality.

but im not sure if we are undertanding each other.

ill try to put it in other words and use another example:

in a brand new fresh install of thunderbird and lightning, you have your own "local" calendar. lets create any kind of meeting in there. its stored localy - i get it. but if u want to invite other people, i would expect thunderbird to "import" my existing calendar meetings into this new "invite" window for my own better time schedule opportunities. why can i see it in the invite window? (see attachet picture).

only way how can i get ito work is using imported gmail calendar. when im using gmail calendar, meetings from "main calendar lightning window" are show correctly in "invite other people" window. it show on my previous image as top right picture and thats what i need at the end of the day :). thanks
