I am having problem with mail flow from on-premises to O365 users. Here is the problem, I am trying to resolve
1. Created O365 user mailbox from Office 365 Dashboard2. Sent email to O365 user3. The sent email stays in the queue at on-premises exchange server 2019
I tried this as well
1. Migrated on-premises mailbox to O3652. Sent email to migrated mailbox user3. The sent email again stays in the queue at on-premises exchange server 2019
I can send email to users internally (within the organization). Any email sent to O365 users does not go through.
I did not change send connectors or receive connectors created by HCW. The only minor change in my environment is, I am using mail relay agent.
Thanks and look forward to your help. I am happy to share screenshot of all the connectors, if you want.
