In reply to David Carter. I would check the configuration in place, as the HCW should have enabled the MRS Proxy endpoint across all servers including the Exchange 2013 servers already for you.

Hi we have 4 existing Mailbox/CAS servers running Exchange 2013. We have spun up two new Exchange 2019 servers to serve as hybrid CAS endpoint and hosting the Arbitration mailboxes and ECP for administration during/after the moves. Do we need MRS Proxy enabled on the Exchange 2013 Mailbox servers too, or just the Exchange 2019 servers where the Hybrid configuration it set to connect to from the External?

Hi Steve,

Great post! Quick question to confirm my understanding.

From what i’m reading here, there would be no requirements to modify the existing Exchange server EWS virtual directory external URL to reflect the new migration endpoints, as long as the public certificate presented by the external IP on the firewall has a valid SAN, correct?

As an example, my current configuration would have the servers reply to mail.mycompany.com. I’d add mrs1.mycompany.com and mrs2.mycompany.com in the SAN and NAT those directly to specific servers and call it a day?

Thanks!

Hiya,

Yes absolutely. This should only need the MRSProxy enabled (Hybrid should have done it to all EWS Virtual Directories, but it can be enabled using PowerShell) and to have an externally published FQDN, with a valid SSL certificate and unique name to the region or server. Then add an additional Migration Endpoint in Exchange Online with that FQDN, and test mailbox moves.

Steve, one question, we have one customer with europe region already with hybrid deployment and they have a mexico region (same internal AD; same Exchange Org, same domain, same ALL) but the mexican mailboxes are on a server located on Texas USA (connected internally to all exchange org and servers across US, EUROPE)

the question is, can I add an extra MRS proxy at USA server (CAS) and call the remote move request to migrate those mailboxes, instead of sending them through Europe?
