Alias: you can send email from an address which is the reply address of your mailbox. You can use address rewriting or similar features to accomplish this.
Hi thanks for mentioning that, hopefully I can get this confirmed.
setting an alias would only allow you to receive to that address? I would want all users to have the same email address for sending/receiving.

- Thanks, that's very promising. So this would mean keeping AAD Connect for syncing local AD account passwords as we currently do with two forests.
Do you know of any good information on how to go about using Aliases and address rewriting to get all users having email@a.com ?As you will keep your on-premises Exchange at least for recipient management, you can use it as an address rewrite gateway:
Exchange Online also supports Address Rewrite, which routes outgoing email through an on-premises gateway that modifies the addresses. This feature enables you to hide sub-domains, make email from a multi-domain organization appear as a single domain, or make partner-relayed email appear as if it were sent from inside your organization. Administrators configure custom email routing within the Exchange admin center (EAC).

Hello Dominik.
Unfortunately the address rewriting feature is not supported on Exchange online.
MS expert said recently: "we don’t have any plan to bring Address Rewrite to Exchange Online."
There exists a non-MS cloud service that implements the sender address rewriting function for Office 365/Exchange online.
