The problem with Calendar does seem to be related to the color of the calendar I use. My default Calendar is designated by a blue dot in settings. As long as I use that calendar to send him invitations, he gets it. If I use the pink (inbox) calendar, or the orange (home) calendar etc.....he doesn't receive the mail. His invites from me always seems to go to his yellow (work) calendar!



Alternatively his mail to me (his default setting shows blue for home) however it appears at this point, he can use any color calendar to send an invite to me.

This is totally confusing to me - I thought I was so clever to set up different colors for the calendars depending upon the category I designated i.e. dr appts are grey, work is yellow, home is blue etc....but somehow the choice of category impacts the invitations to events?????

I can live with it as long as I remember the correct color to use when I invite him to an event :( :(
