Hi everybody,

As the title says I'm experiencing critical problems in restoring my emails and account after a time machine total restore. These are the steps of what happened:

I was experiencing serious problems with OS 10.8.2 after the major update (I really blame Apple for this... recent software updates are a disgrace one more than the other) so I really needed to do a full restore. 
My Mac is always totally backed up with Time Machine on an external USB drive, so I felt confident and safe not to lose any of my data.
I performed a total OS reinstall from the Recovery Partition of my Mac. Doing this initialized my HD and reinstalled Mountain Lion from scratches. 
At the first boot of the newly installed OS I've opted for a restore form a Time Machine Backup in the Migration Agent options. 
When the system booted again after the restore the very first thin that was displayed was a red Outlook Error (coming probably from the sync agent) that was asking me to rebuild my Outlook Database. I accepted to perform the Rebuild and it begun.
The Rebuild proceeded till point 4 of 5 when it interrupts and display the message "Your database could not be rebuilt. [-18000]" and then exits.
After that i launched Outlook and it asked me again to rebuild the Database. The process started once again but it failed in the same way.
I've checked the content of the folder: /users/myuser/documents/Microsoft User Data/Office 2011 Identities and thankfully all my messages and data are still there!! The only thing that is missing is the "database" file that office is unable to rebuild.
Is this a known problem? 
There is a known procedure to solve that or any other workaround? 
At this time my entire 10 years old database is unusable and this is really a critical problem for me so any kind of help would be much appreciated.

PS Sorry for the very long post but I'm Italian and I have some difficulties expressing myself in concise and short sentences.
Thanks in advance for any answer
