Hi,

I am setting up a Hybrid Wizard config mail migration from on-prem to exchange online. I am using the Modern Hybrid Topology.

I get a Validating Hybrid Agent for Exchange usage error:

I have also added the log file for further details of this error.

Guidance to resolve this issue will be highly appreciated.

    Hi @Jabulani Motloung ,

    Connect to Exchange Online PowerShell and run the command below after replacing "domain\admin" with the on-premises migration admin you are using:

    Test-MigrationServerAvailability -ExchangeRemoteMove: $true -RemoteServer 'dd500728-4fec-405f-a706-a3b245576f1f.resource.mailboxmigration.his.msappproxy.net' -Credentials (Get-Credential -UserName domain\admin)

    If you get the same error, check the Hybrid Agent Status (ACTIVE or INACTIVE) by re-running Modern HCW and check it in the GUI, reference here.

    If the Hybrid Agent is ACTIVE, check and confirm with Performance Monitor that you see the requests. If the request counters (for #of requests) go up on the Agent machine when you do Test-MigrationServerAvailability to the Hybrid Agent, it's likely to be an issue with the on-premises infrastructure, especially proxy and firewall settings. Then please go through the links below and make sure all the requirements have been met:

    Reference: Troubleshooting Hybrid Migration Endpoints in Classic and Modern Hybrid -Scenario 1: Test-MigrationServerAvailability fails because of connectivity / timeout errors.
