Multiple autodiscover for a single domain

[Deleted]

Hi everyone,

I'm planning the Exchange migration from a provider (shared exchange server) to Office 365 (on our own account).

Our actual provider uses a record SRV for autodiscover : 

_autodiscover._tcp        3600      IN           SRV        0             0              443         mail.XXXX.com.

For O365 :

CNAME autodiscover autodiscover.outlook.com

Is there any way that i can do in order to get autodiscover for both platforms with a single domain ?

Thanks a lot and best regards,

Anthony

If it's a shared server, they should have different domains still thou?

May I ask why you want to have two different autodiscover records? If you are migrating using hybrid technique, the autodiscover record should point to your onprem server until you conclude the migration
