Regional Name Resolution for Office365.com
We have two Offices one in US and other in India, both sites have Domain controllers (Win 2012) and have one Public DNS server (BlueCat) sits in US. We are planning to migrate to Office 365 and migrated few pilot users. Currently users in India connects to the US regional data center servers using outlook, because then they resolve the Outlook.Office365.com it resolves the US IP's as our public server sits in US.
Currently I have added the HOST file entries in user desktop/laptop to connect to Indian Regional data center, Question is what are my other option to redirect the traffic to local region data centers with out using the HOST file.
PS : Implementing a public DNS server in India office is a bit expensive solution so we have kept it as a last resort.

Mulit-Geo will definitely help, but I heard it's going to be pretty expensive compare to normal tenancy.
With regards to current situation, Latency to US is much higher than to the Indian datacenters and Microsoft has much better connectivity between their datacenters. As per the outlook troubleshooting log analysis it takes less than 2 seconds to process a packet with in the Microsoft network which is good.
Right now I am trying to see if any possible way to redirect the outlook clients to the regional O365 servers.

The system is in preview at the moment, but should resolve many of your issues once it's made more available. If you can't get Multi-Geo, you would either need to retain On-prem systems for India or configure a separate O365 tenant that is licensed for the India region to meet data residency requirement.
Note that just pointing DNS records to the India datacenters for O365 would not meed residency requirements, since the data would still reside in the US or wherever the O365 tenant was originally licensed in.
