Problem with migrating IMAP mailboxes to Exchange Online.
Hello, I have a problem with migrating IMAP mailboxes to Exchange Online. I created several migration tasks via "Migration Batch" but most of them fail because some of the mails e.g. 10 out of 1000 ...
No one replied because there is no way to fix this. You can start the migration batch or use SyncNow and it will sync again, and go through one good sync, but it will just say Failed again. So you basically have to switch your MX records and give it enough time and then do one final sync and when done delete the batch.
