I just got a mail from someone notifying me of an out of office reply she received after she sent a meeting request to 3 different people, not including the one that's on leave.
She said my colleague (who is out of the office himself and who I won't bother for unimportant things) knew about this in the past, but I'm not sure what it could be.
The only thing I can think of is shared calendars of some sort.
Does anyone have an idea? Br
