I would like to know that whether there a way to integrate Office 365 users with the on-premises active directory, with both having different domains. The on-premises active directory has the domain, for e.g. XYZ.COM whereas the domain integrated with Office 365 is XYZABC.COM. We are using the latter domain for our emails.
Now, I would like to know whether is it possible to integrate Office 365 with the local on-premises active directory, so that the clients can login (either PC or email server) with a single sign-in.
Seeing the difference in both the doamins, kindly advise what options do I have and what shall be required to complete this.
