Steve,
If you copy those control files from the previous version you might undo the security patch for Exchange.
That hotfix was updated in November to add the .60 folder and we do not have a hotfix yet.
You should still be able to recall archived items, just the buttons and icons are missing.
I would suggest you open a case w/ support and request updated control files for .60. There are a few people out there w/ the same issue, so the more request there are for it the higher up the priority list it goes.
Cheers,
Tony
