Enterprise Vault: useful query to find the date range of emails stored in the index

(... run against the Vault Store database...)

SELECT MIN (recordcreationdate) AS 'Oldest Item Date'
, MAX (recordcreationdate) AS 'Youngest Item Date'
FROM JournalArchive

WHERE IndexSeqNo BETWEEN 121649147 AND 126649435 '(numbers found in the Enterprise Vault Admin Console for Index Volume)'

Lync: Get-CsManagementStoreReplicationStatus does not display information after CSManagementStore moved from Lync 2010 to Lync 2013

After successful move of CSManagementStore from Lync 2010 to Lync 2013, Get-CsManagementStoreReplicationStatus runs without any errors, but without results either.

Turns out that replication is broken after moving CSManagementStore due to the fact that "Lync Server Master Replicator Agent" service is not started on Lync 2013 Front End Server.

Starting "Lync Server Master Replicator Agent" takes care of the issue.
