The onprem user does NOT have the Cloud user in Junk Mail or in the Block list. I added the cloud user to the “Safe Sender or Recipient List” but the Edge Server still blocks the cloud user when sending to that one onprem user. Is there a way I can force the Edge Server to accept email from that Cloud user?

Have you tried? That’s the best way to find out.

sorry for an incorrect carriage return

get-mailboxjunkemailconfiguration -identity username | select-object BlockedSendersAndDomains -Expand BlockedSendersAndDomains | out-file “C:\Users\Public\Documents\list.txt”

Or you can expand the list explicitly to a file:

get-mailboxjunkemailconfiguration -identity | select-object BlockedSendersAndDo
mains -Expand BlockedSendersAndDomains | out-file “C:\Users\Public\Documents\list.txt”

How to remove the usage of safelist aggregation on the exchange environment, since the desactivation of the contentfilter does not solve the issue.

Thanks a lot
