Dear Team We are trying to setup Hybrid Office 365 . But few IP ranges in Microsoftonline.com is same i our on prem. For example Microsoftonline is having ip range 20.x.x.x and in our onprem we have also 20.x.x.x subnet/vlan. So once we login it goes to our internal dns/core switch and does not resolve login.microsoftonline.com sites. Please advice how to get rid of this without changing our vlan.
