when it comes to using New-MoveRequest, New-MailboxImportRequest and commands like this, you have a -LargeItemLimit switch that works with -AcceptLargeDataLoss .
the question is, How large is "large"?! how big an item must be before it is considered "large" and getting skipped?
second question: is that only the message body, attachement, or message body+attachment that would make this size? I assume it is body+attachments, but asking to make sure.
third question with regards to the first one: how would you change this "large" threashold?
