In my case, before the reconstruct had finished, I had several problems
which might be not acceptable for large organizations.

For example, users could not move messages between folders in their
mailbox. I would consider this quite basic functionality, because
deleting a message (with most clients) also means moving it (to trash).
Functionality was back not before the reconstruct had finished completely.

If interested, please see the respective thread from yesterday / today
for details (I don't want to clutter the list by repeating all that
stuff here).
