Emails under same tenant have been blocked

Situation: the client is internal company and has migrated their multiple domains into a Microsoft Tenant. Now, they have an issue to send emails between domains. For example, A.com and B.com are under the same Tenant with default domain name C.com. Email sent from A to B was blocked.

Cause: They encountered this issue during the migration of A.com and B.com to C.me. Although I am not entirely certain about the reason, I have a theory. Both A.com and B.com are under the Microsoft Tenant. When A.com sends an email to B.com, Microsoft Intelligent Assistant (which is not as intelligent as a human) mistakenly identifies the email as spam and blocks it.

Resolution: Add A.com, and C.com to whitelist. Please refer to these posts:

SonicWALL Global VPN Client is connected and authenticated but can’t access internal LAN resources

Troubleshooting:

  1. The user/group may not have access to LAN subnets. In our case, the client adds All Interface IP instead of LAN Subnets. We fix the problem by replacing All Interface IP with LAN Subnets.

2. The SSLVPN IP Pool is in the same subnet as X0.
