Can I use AD synch with Office 365 if I have an on-prem Exchange server?
Hello -
My current environment has a Windows 2008R2 Server running Exchange 2010. Please note that at one point it was incorrectly setup as domain controller in addition to running Exchange. We want to remove this server.
We also have a separate Windows 2012R2 Domain Controller. We want to retain this server.
We are also in the process of moving towards hosted Office 365. We will be doing a cutover rather than migrating. So we will never be in a hybrid mode.
That said, my question is this. In the past I have setup new servers with an Office 365 connector (Dir Synch?). However, I have not done this with a server that has an on-prem Exchange Server.
The fact that we have an unsupported infrastructure (DC with Exchange) makes me hesitate to introduce something new. However, I wanted to know if we can use Office 365 Dir Synch when the AD already has an internal Exchange server.
Thanks in advance.

All great feedback. Thank you so much everyone. Not sure how I could have given everyone "Best Answer".

I've already created all my users and groups on O365; and Outlook profiles on my client workstations in preparation. I have not setup the default domain yet.
- Would this overwrite everything that I've done?
- Is it an option to setup Azure AD Connect at a later time?
