this solve the opening issue but the worse from my point of view is
when I come back from the calendar I wish to in a different place then
the one I was at.
Here is the Problem:
I have many personal folders and they fill my screen (when the main
folder is closed), what I did is made a "Favorite Folders" of Inbox,
draft, sent items and deleted items, then collapsed the main mail
folder and opened the personal folder in a way that I can see all the
interesting folders.
Now, when I read messages from the inbox (in the favorite folders)
then
go to the calendar and back to "mail" my main folder is expended and
my
focus is on the inbox of the main folder and not the inbox of the
"favorite folders".
What I want is either to make the main folder remain closed and stay
with the focus on the inbox of the "favorite folders" (best option for
me) or when I get back to the mail from the calendar get focus on a
different folder then inbox.
