    Great post, thank you. This helped me when both RecoveryItems and DiscoveryHolds were full. We had a lot of retention policies, so using this command excluded them from all polices:

     

     

    Get-RetentionCompliancePolicy | foreach {Set-RetentionCompliancePolicy -identity $_.name -AddExchangeLocationException <user>}

     

     

    Also, it can take a lot more than a few minutes if the mailbox has a lot of items (in my case, 100GB). It's going very slow for me, maybe 1GB every hour or two.

This is working perfectly! I came in this morning and the deletions had stalled, tried your method of running it twice every 5 minutes and it's dropped from 99GB to 58GB in about an hour. Here's a snippet to do this every 5 mins automatically, and report the size of the folders:

while ($true) {
    Start-ManagedFolderAssistant -Identity <email address removed for privacy reasons>
    Start-ManagedFolderAssistant -Identity <email address removed for privacy reasons>
    sleep 300
    Get-MailboxFolderStatistics <email address removed for privacy reasons> -FolderScope RecoverableItems | Ft Name,FolderAndSubfolderSize
    }
