Hi
We just noticed our autodiscover is pointing to an old server that has been decommissioned.
The MX and SPF record for the same domain point to exchange online. Our SPF record does contain some IP's and mailers etc.
What would be the impact in this case of removing the incorrectly configured autodiscover and pointing it to exchange online?
Or would it be better changing the IP of the existing record to point to our actual on prem exchange server?
We do not have any mailboxes on prem but we relay etc for 3rd partys and certain programs via this on prem exchange server
