Missing Sent Items after IMAP Migration
Hello,
I current did a migration from IBM Domino onpremise mail server to exchange online.
The migration is still underway but there are some earlier migration batches (used IMAP as migration method) that show the sync is perfect and even shows number of items migrated. On the users end they are only able to see all their inbox mails from the previous mail server (IBM Domino).
What could be the issue in this case? I have done multiple migrations but haven't seen such an issue before.
Any ideas are highly appreciated

Hi, it usually happens because IMAP import only takes Inbox subfolders or doesn't recognize the “Sent Messages” folder. To fix:
Leave the Root folder path in IMAP endpoint empty (or set “/”).
Rename the Sent folder to “Sent” or map it manually with -IMAPFolderSent.
Check with Get-MigrationUserStatistics how many items ended up in each folder.
If it still doesn't work, export the Sent folder to PST from Domino and import it with the Mailbox Import Service.
That way you should see the Sent Items as well.
Hello Micheleariis,
Thanks for your feedback. I will give this a try and see if it works.
I will update.
