$legacy =Get-Mailbox -RecipientTypeDetails LegacyMailbox
$legacy | sort Database | Group-Object -Property database | select count, name
$legacy | sort organizationalunit | Group-Object -Property organizationalunit | select count, name

Get-MoveRequest | Get-MoveRequestStatistics | sort status, TotalMailboxSize
$moves=Get-MoveRequest | Get-MoveRequestStatistics | sort -Property lastupdatetime
$moves | select DisplayName, TotalMailboxSize, alias, lastupdatetimestamp, TotalInProgressDuration
$moves | measure -Property totalmailboxsize -sum
$moves | where {$_.status -eq "Queued"} | measure -Property totalmailboxsize -sum
$($moves | where {$_.status -eq "Queued"} | measure -Property totalmailboxsize -sum).sum / 1073741824
$($moves | where {$_.status -eq "Queued" -and $_.targetdatabase -eq "Mailbox Database 2"} | measure -Property totalmailboxsize -sum).sum / 1073741824
New-MoveRequest -TargetDatabase "MDB1" -BadItemLimit 50 -Identity blah@blah.com

Mailbox Statistics

$MDB=Get-MailboxStatistics -Database "Mailbox Database 1"
$MDB+=Get-MailboxStatistics -Database "Mailbox Database 2"
$MDB | where {$_.TotalItemSize.Value.ToMB() -gt 2048 } | sort TotalItemSize | select DisplayName, TotalItemSize
$MDB1=Get-MailboxStatistics -Database "Mailbox Database 1" | sort TotalItemSize
$MDB1 | select DisplayName,
    @{Name="PrimarySmtpAddress";Expression={((Get-Mailbox -Identity $_.identity.MailboxGuid.Guid).PrimarySmtpAddress.tostring())}},
    @{Name="TotalItemSize";Expression={($_.TotalItemSize.value.tokb())}}

Export Mailbox

$date = (Get-Date).adddays(-60)
New-MailboxExportRequest -Mailbox kcurran -ContentFilter {(Received -gt $date) -or (Sent -gt $date)} -FilePath "\\exchange1\TemporaryPSTs\kcurran60days.pst"
When running the command above it does not seem to filter properly

Get-MailboxExportRequest | Get-MailboxExportRequestStatistics | fl ContentFilter
ContentFilter : ((Received -ne $null) -or (Sent -ne $null))


New-MailboxExportRequest -Mailbox kcurran -ContentFilter {(Received -gt "7/29/2011") -or (Sent -gt "7/29/2011")} -FilePath "\\exchange1\TemporaryPSTs\kcurran60days.pst"



Notes / links

Manual export to PST due to bug trying to move mailboxes to Exchange 2010 SP1 Spent 2 months trying to work with MS on issue
When you export to pst calendar items get a "Copy: " prefix this link has vba code to remove it.
