mail erased by synchronization

[Angelo Maragna]

Hallo everyone.
I had had to restore Exchange databases to a previous backup (about the
first days of december).
After reconnecting outlook clients all new mails started disappearing.
Now it seems we have lost all mails, but ost file size in almost all clients
is bigger than mailbox size in exchange server 2007.

All clients uses outlook 2003 on windows xp.

I have two questions.
1. Why exchange synchronization erased the newer items?
2. Is there a way to recover items from the ost (local versions?)

Thanks to all

Angelo

1) From an Outlook point of view, the messages have been deleted on the
server (they were there the last time Outlook synced with Exchange and now
they are no longer there) and therefore the changes are being reflected to
the client. Now, if you created new items during this period or made changes
to local items, then these would be new to the server and therefore
uploaded.

2) As long as the "white space" hasn't been reused yet by other items or
truncated, you could try to recover them with specialized recovery tools.
Mind you; these don't come cheap! However, I had good results with this
tool;

If you decide to order use DNC-APME-HT to get a discount.

Note that because of the storage efficiently of Exchange, ost-files are
usually already 25% larger than the Exchange mailbox size even without any
white space in them or items to recover.
