A Forum reader recently asked ...
"I have a user who accidentally archived her entire calendar using the
Mailbox Storage Size Information GUI. Is there a way we can unarchive her
calendar, without doing it one item at a time?"
And here's the reply from Joe Marton ...
1. Change the calendar display to View by Details instead of View by Calendar.
2. Highlight everything.
