Office 365 Directory Based Edge Blocking support for on-premises Mail Enabled Public Folders
we implemented this feature in our environment and have some warnings on DeltaImport profile. It looks like it related to on-premise mail public folders that are members of on-premise distribution groups.
Every Delta import prompts the following warning messages in the Synchronization Service manager console:
'completed-warnings '- exported-change-not-reimported
- Aleh,
We will investigate this scenario. Few questions:
1) Currently, when a mail is sent to on-premise distribution groups, is it being delivered to mail Public Folders (which is part of the distribution group)?
2) You are getting "completed-warnings - exported-change-not-reimported" only for mail Public Folders which are part of distribution groups & not for other mail Public Folders. Am I right?
We may need more info during the investigation. If you are interested, you can reach out to us at the following alias for further communication modernpfmigrationtoexo@service.microsoft.com. You can send the entire error message so that we will know the exact nature of the issue.

- if you as sender located onpremise - yes. if mail send from o365 - No, because on o365 side DG does not contain PF as member (membership is not completely synconized).
2) You are getting “completed-warnings – exported-change-not-reimported” only for mail Public Folders which are part of distribution groups & not for other mail Public Folders. Am I right?
Not sure, for we remove this feature from production, but it possibly yes.
To sync mailPF to o365 we use now Sync-MailPublicFolders.ps1 as partial solution (sync mail addresses, not membership).
