Is your exchange server running in a cluster mode ?
Check the exchange server DNS logs, it is probably a DDNS update issue.
Then look in the syslog of the Infoblox server and look for DDNS update errors
They should point you in the right direction.
The usual fix is to either check the DDNS update ACLS on the zone. Or locate the DNS records for the exchange server in Infoblox, and either delete them (so the DDNS update can put them back correctly) or switch them from HOST records to A & PTR.
