Outlook preview is not available

X1 8.3.1.1 5003AZ
Outlook 2010
Win 7 64bits

Preview pane shows for several (pretty old) mails:
"Outlook preview is not available. The item may have been deleted or moved.
The connection to Outlook may also need to be refreshed. Use the Menu->Exit option and then relaunch X1 Search to try again."


The mails do exist, have not been deleted or moved. X1 opens them
Restarting Outlook, X1, rebuildilng index does not help - in any order.

Seems to be affecting all mails before 6/2010 or so.

Annoying...
