Its not the actual archives, it is the items within the consolidated one following a move archive + deletion of the closed one. The items have the same date and content. What happened was this:
- The move archive process was tested, we confirmed item retrieval, shortcut move was ok. The closed archive with the date range, name and status was 'closed'. The closed one was deleted and subsequent item retrieval was proven to be ok
- Due to various pressures a big bang approach was used to mass migrate all other user archives over christmas. The old ones were the same with a closed status and date range 'stamp'. Using the move archive text report files in the reports directory, there were a handful or errors against most mailboxes, but these were dismissed as corrupt data, certainly when moving tens of thousands of items per mailbox a few problems are to be expected
- All the closed ones were mass deleted
- Users complain that their shortcuts dont work. I then realise that for 90% of the moves, none of the shortcuts updated. A SQL query and EV report confirmed this
- I read there were various solutions to repair shortcuts, so I chose the PST export, reimport and removal of orphaned shortcuts - appearing the best way to do this 'on mass'. This resulted in all users having a consolidated archive each but with all items inside their mailbox duplicated, when viewed from archive explorer
The majority of users here don't even know what archive explorer/EV search is, most just double click shortcuts in Outlook. However there may be situations where duplicated items in the archive may cause future issues such as a wider adoption of these tools or a future export to PST of the archives.
So there is one shortcut in the users Outlook view, but the same item twice in archive explorer/archive.
I should also mention that this is EV 10.0.2.
