Microsoft Finally Makes Send Mail from Alias Generally Available
Nearly five years after going into preview, Microsoft has made the send from alias feature for Exchange Online generally available. It’s a very useful feature that eliminates the need to use a shared mailbox to be able to send messages with different email addresses. Microsoft has closed some functionality gaps since the preview started, but sending from an alias is not the same as sending from a mailbox’s primary SMTP address. Some user training might be necessary!
