BESA did not have an exchange box.
I fixed that, and the old "brick-style" method worked.
However, If I try a restore from tape, I still can't open the Mailbox Store.
Maybe I'm doing something wrong:
I insert the tape, I inventory the tape.
Then, in the media tab, I right-click the tape volume and choose "restore."
I then choose the backup set I want, which is a backup of the Information store. I click the + next to it, and it opens up to Mailbox Store and Public Folders Store, both with +'s next to them. I click the + next to Mailbox store, and the only thing that happens is that the + goes away.
What am I doing wrong?
