The items might be missing from the archive’s Metadata Store.
This can occur if:
Items that are missing from the Metadata Store can be identified using the Get-EVMDSStatus PowerShell cmdlet with the –IncludeMissingItemsparameter.
You can also pipe the output from Get-EVMDSStatustoNew-EVMDSBuildTask to add the missing items.
Example:
C:\PS>Get-EVMDSStatus -VaultStoreId 1CAD4933D9987A111B3E42E26A71984301110000@ev -IncludeMissingItems | Where-Object {$_.MDSStatus –ne 'EV_MDS_DISABLED' -and $_.MDSMissingItems -gt 0} | New-EVMDSBuildTask -Mode Build -Force
This creates a Metadata Store build task for each archive from the specified vault store that is enabled for IMAP access or for fast browsing, and that has items missing from its metadata store.
IMAP access and fast browsing are disabled for each of the archives until the associated EVMDSBuildTask has been completed.
