Use a screen reader to configure mail flow rules in the Classic Exchange admin center in Exchange Online
Using a screen reader and keyboard shortcuts, you can create mail flow rules (also known as transport rules) in Exchange Online in the Classic Exchange admin center ( Classic EAC) to look for specific conditions in messages that pass through your organization and take action on them. The main difference between mail flow rules and Inbox rules you would set up in an email client application (such as Outlook) is that mail flow rules take action on messages while they're in transit as opposed to after the message is delivered. Mail flow rules also contain a richer set of conditions, exceptions, and actions, which provides you with the flexibility to implement many types of messaging policies.
Note: To learn more about mail flow rules, see Mail flow rules (transport rules) in Exchange Online.
