Hi,
Im in the process of migrating shared mailboxes into O365. When setting up a migration batch, I have left the "Bad item limit" and "Large item limit" blank so it capture all errors. Almost with every mailbox I'm noticing items skipped
with the description "Corrupt Mailbox Security Descriptor" the numbers vary for each mailbox. Wondering if this error is related to a Legacy permission on these mailboxes. Is there a way to troubleshoot these types of error. Maybe a application or
PowerShell script i can use.
