Hello,
I have an Exchange Server 2016 environment that I am migrating to Exchange Online. The hybrid configuration has already been done.
Meanwhile, users migrated to Exchange are seeing their emails spammed when they send to other Exchange Online users belonging to other Office 365 tenants. Before the migration they did not have this problem.
If someone can help me to find the cause of the problem.
Regards

SPF is well configured but DKIM and DMARC are not configured?
Yes, agree with Andy, please follow the guide in the official document to configure the DKIM and DMARC record firstly then verify the result again.
