Thanks for this!

Or.. just use Set-ADServerSettings -ViewEntireForest $True first to make it search the entire forest.

Dude you saved me from pulling what hair I have let out. Thanks for this post!!!

(Get-MailboxExportRequest | ?{ $_.RequestQueue -eq “DatabaseName” })|%{Remove-MailboxExportRequest -identity $_.identity }

(Get-MailboxImportRequest | ?{ $_.RequestQueue -eq “DatabaseName” })|%{Remove-MailboxExportRequest -identity $_.identity }

Then, for good measure, I ran:
Get-MailboxStatistics -Database “DatabaseName | Where { $_.DisconnectReason -ne $null } | ForEach { Update-StoreMailboxState -Database $_.Database -Identity $_.MailboxGuid -Confirm:$false }

Marcina

(Get-MailboxExportRequest | ?{ $_.RequestQueue -eq “DatabaseName” })
and
(Get-mailboxImportRequest | ?{ $_.RequestQueue -eq “DatabaseName” })

Once those were removed, I was able to delete the database without issue.

Hope that helps!
