You asked, <b>&quot;Is it now possible to have the user send from their chosen &quot;From&quot; address with only one mailbox?&quot;</b><br />
<br />
Yes.<br />
<br />
This is handled inside each user's mail client configuration.<br />
<br />
1) Each account will have it's own outgoing SMTP connection defined.<br />
<br />
2) User selects any From: address they like.<br />
<br />
3) User then selects the outgoing SMTP definition to use.<br />
<br />
So, can you do this?<br />
<br />
Yes.<br />
<br />
Does this make sending every... single... email... a laborious chore?<br />
<br />
Yes.<br />
<br />
Suggestion: Describe what you're actually trying to accomplish. Your real world situation.<br />

As a workaround you can create as a new mailbox with whatever email address and give permission.<br>Not possible to send from alias as of now.<br>Only supported by Exchange Online.
</div>


<div>
Lets say, it may be a question of handling. <br>If you add a second mailbox, the user can use the second mailbox like its own and even need not take too much care, how the mail is send. <br>Means if he activate hsi first mailbox, he sents out with the address of the first mailbox, if he chooses the second, the second address is used. <br><br>This makes handling for the user much easier.<br>As far a s the user has actively to change something, it will happen regularly that users are sending with the wrong sender address. &nbsp; &nbsp;

Ive seen answers for 2007 and earlier, but never for Exchange 2016, so im wondering if its now possible. Some sources say no, but would like other opinions.<br>So we have multiple domains on our On Prem 2016 Exchange (3). and currently no user has the ability to send from any domain they choose, only their primary. They can receive all their different domain addresses via their aliases in their current mailbox.<br>Is it now possible to have the user send from their chosen "From" address with only one mailbox?<br>I know i can add a user account for each domain and assign "Send As" and add a forward rule. And i also have the option to have a distributed group for a users "alternate" email address but with 3 (maybe going 4) domains and over 100 users, just thinking of resources and setup time. Using outlook 2016 as mail client but with owa for anywhere access and also outlook as their mobile phone email client. The 'powers that be' want one mailbox for each user, do i tell them its not possible currently and the only options are what ive mentioned?<br>Cheers<br><br>
