did exchange online change from srv records for autodiscovery to cname records?


When we had onprem exchange we used srv records _autodiscovery.

We now have a hybrid exchange but all the mailbox are on o365 so I was thinking of updating DNS to match (MX records already moved)

When I check the admin center for DNS setting they only list a cname for autodiscovery, not a srv record.


Just wondering when they stopped with the srv record and can I remove them and use the cname now?

SRV records have not been supported for Hybrid afaik, ever. Just configure the CNAME one.

I only have the srv records from when mailboxes were onprem.
