Archive Mailbox Statistics

Although Personal Archives in Exchange 2010 are often in cheaper storage than “normal” mailboxes, we still need to keep an eye on them to check how archives are growing and how (if!) users are using it.

Here’s a simple script to get some statistics regarding all the archive mailboxes in your environment:

$mbcombCollection = @()

$archiveMbxs = Get-Mailbox -Archive -ResultSize Unlimited | Select Identity, ArchiveWarningQuota, ArchiveQuota
ForEach ($mbx in $archiveMbxs)
{
 $mbxStats = Get-MailboxStatistics $mbx.Identity -Archive | Select DisplayName, StorageLimitStatus, TotalItemSize, TotalDeletedItemSize, ItemCount, DeletedItemCount, Database

 $mbcomb = "" | Select "Display Name", StorageLimitStatus, "TotalItemSize (MB)", "TotalDeletedItemSize (MB)", ItemCount, DeletedItemCount, Database, "ArchiveWarningQuota (GB)", "ArchiveQuota (GB)"

 $mbcomb."Display Name" = $mbxStats.DisplayName
 $mbcomb.StorageLimitStatus = $mbxStats.StorageLimitStatus
 $mbcomb."TotalItemSize (MB)" = [math]::round($mbxStats.TotalItemSize.Value.ToMB(), 2)
 $mbcomb."TotalDeletedItemSize (MB)" = [math]::round($mbxStats.TotalDeletedItemSize.Value.ToMB(), 2)
 $mbcomb.ItemCount = $mbxStats.ItemCount
 $mbcomb.DeletedItemCount = $mbxStats.DeletedItemCount
 $mbcomb.Database = $mbxStats.Database
 $mbcomb."ArchiveWarningQuota (GB)" = $mbx.ArchiveWarningQuota.Value.ToGB()
 $mbcomb."ArchiveQuota (GB)" = $mbx.ArchiveWarningQuota.Value.ToGB()

 $mbcombCollection += $mbcomb
}

#$mbcombCollection
$mbcombCollection | Export-Csv D:\Scripts\Reports\"ArchiveStats_$(Get-Date -f 'yyyyMMdd').csv" -NoType

Hope this helps!
