I was asked to do the following.
1. Set up an Azure server and join it to the on Premises domain.
2. Install the Active Directory Synchronization tool in Office 365
3. configure DirSync
4. synchronize Microsoft 365 to the on premises domain controller using the Azure server as the go between.
I have never done this before and was wondering if anyone can help me know how to proceed.
There is a concern that since the Premises server is created first and then Microsoft 365 the existing mailboxes will be wiped out.
Is that a possibility or is there a better way to go about doing this task?
