EV not removing shortcuts and leaving duplicates in user's mailbox
today i stumbeled upon a pretty strange issue when restoring content into a user's mailbox - after the restoration run, it turns out that there are lots (586) shortcuts left, even thotugh the original item was restored successfully and the option to remove the shortcut was selected. Further more if the shortcut itself is selected and "Restore from Vault" is pressed, then the item is restored into the folder a second time (see te pic attached). I forced a seperate "Shortcut processing" run for this specific user (and we have the reg key that instructs EV to delete orphaned shortcuts), but the shortcuts are still there. Then I decided that there might be something wrong with the user's indexes, so i forced a rebuild or the indexes, but the shortcuts remain, as well as the duplicate items.
EV version is 9.0.4 in clustered mode. Exchange is 2010, Outlook is 2010. OS is Windows Server 2008 R2.
P.S. Also, I'd like to ask what are Symantec's recommendations on massive restorations (~90 000 items need to be restored), as well as how to restore only the shortcuts, and no extra content?
