New-MailboxImportRequest -Status Failed | Set-MailboxImportRequest -BadItemLimit 50

Set the parameter “Bad Limit” up to 10 or below. But if you want to import more corrupted items till limit, then you can use additional parameter is known as “Accept Large Data Loss”

New-MailboxImportRequest [-Mailbox Name] <LargeItemLimit 100 AcceptLargeDataLoss > -FilePath

Get-ReceiveConnector | Set-ReceiveConnector -MaxMessageSize 100MB
