The error is presented when searching for items in EV for only some mail:
No preview of this item is available.
(Error Code: 0x80004005)
Are there any log files that I can inspect to investigate the issue?

Also I currently have no access to my workspace, this error hex code reminds me of an Issue with has been fixed in EV 12.2.3
CFT 727. This was an issue with EV Search and FolderVisible attribut in Exchange. For which items in which exchange folder class does this error appear? Can you regular open the item? Index is healthy, too?
Remember, also some itemtypes are limited in preview pane.
