Okay people maybe this can help all of us that have lost our calendars..
Down at the bottom are 3 icons: notes folder & and arrow. click on the
folder icon.
On the left side pane is a directory tree. (Mailbox, contacts, deleted
items, Inbox, etc.) Look for an icon of a calendar especially in deleted
items. If it is there you can click and drag to mailbox or contacts. (I
even accidently put mine in appointments. I forgot one thing, there may your
calendar icon already there, but you can't access it. What I did was drag
and drop my calendar onto the calendar that I could not open....WHALA! when
I went to the Calendar and there it was opened and all purdy with all my
appointments. When I went to set me a reminder (we have an intranet) this
time it reminded me instead of saying something like it couldn't remind me
because I didn't have it in my calendar or my tasks.

I hope anyone who needs this will find it helpful. I worked on this for
almost 1 1/2 days looking for assistance and not finding anything. Trial and
error!!!!
