Archived emails with attachments - The item is no longer in the vault
We've got a problem where a number of users have attempted to un-vault email items with attachments and get the messages below:
Top of email: "There was an error loading this item -- some functionality may not be available"
Double click grey banner: "The item is no longer in the vault"
When viewing Archive Explorer: "The XML returned for the tree view is not as expected. (500)"
This only occurs for emails that were received and archived within a particular timeframe, approx September - October and initially thought it to be an isolated case when the first user logged the problem, however two others have now reported the same problems.
I'm concerned this is a widespread issue and we're unaware of the true extent. The problem has been logged with enterprise support and they've said we need to identify the saveset ID for each affected email and recover the DVS file manually from backup if missing. Once this has been done, we need to run EVSVR command to "Repair > RecreateMissingDBReferences" to re-add the SQL DB references.
The suggested solution could involve hundreds or thousands of mans hours and potentially over years to recover the data, which is obviously not practical and a great concern! I don't like having to rely on backups to recover the emails either.
I've requested that the call be escalated for other suggestions or solutions.
Has anyone else had the problem or can suggest a fix?
Thanks in advance.
