The e-mail migration tool within the Exchange Online control panel has enabled us to migrate mailboxes from a legacy imap system to Office 365.
Some of the user mailboxes have reported a number of "skipped items".
Is there anyway of getting a report out of the migration that tells us which items were skipped?
I have looked at the GUI and have not found a way of identifying the skipped items. I have also tried the powershell cmdlets get-migrationuserstatistics, get-migrationbatch, get-migrationstatus and get-migrationuser. None of these appear to give me details on the specific items skipped.
I know that one reason for skipping items is if they are larger then 25Mb. So one apprach is to go back to the source mailbox and serach for all emails >25Mb. Are there any other reasons why an email will be skipped?
