How to send email from a different address in Outlook 2016

If you have the necessary permissions to send emails from multiple accounts, Outlook makes it easy to change your sending email address -- the one that shows up in the "From" field in the recipient's email box.

The instructions below will walk you through changing your "From" email address in Outlook 2016.

- In Outlook, click the New Email button.
- Click the From button in the email header area.  (If you don't see a From button, see below for how to enable it.)
- If the email address you want to use appears in the drop down list, select it.  Otherwise, select Other E-Mail Address....
- Type the email address you want to use, or click the From... button and select it from the address book.
- Click OK.

If you select an email address that you don't have rights to use, your email will not go through.

---

If you don't see the From button in your compose email window, you'll need to enable it first.  To enable the From button:

- In the New Email window, select the Options tab.
- Click From in the Show Fields section.

The From button should now be visible.  It will show up by default from now on.

What to do when the Attach button in Outlook Web App doesn't work in Chrome

If you are using Outlook Web App for your email through Chrome and the Attach button does not work when you are composing an email, there is an easy fix for this problem (though it's only a short-term fix).

The reason the Attach button won't work is because the Microsoft Silverlight plugin is either not installed or has been disabled.  Chrome will soon be discontinuing the use of Silverlight and other NPAPI plugins, but in the meantime you can enable Silverlight and make use of OWA's attach function.

If you need to download Silverlight, you can download it from Microsoft here.  Once you have it installed, this article shows you how to enable Silverlight in Chrome.

As a workaround, if you can't install Silverlight for some reason (or don't want to) when you log into Outlook Web App, select the "Use the light version of Outlook Web App" option (below where you specify if you are using a public or private computer).  When you run the light version of OWA, attachments are loaded differently, and you can add an attachment to your email without Silverlight.

UPDATE: Here is a simple JavaScript workaround to bring the attachment functionality back to OWA in Chrome, without having to use the light version:

How to create a signature in Microsoft Outlook Web App

Microsoft's Outlook Web App lets you check your mail in Outlook, from any computer with Internet access and a web browser.  If you want to set up an email signature in Outlook Web App, here's how:

- Open a web browser and log into your Outlook Web App mail account
- Click Options in the upper right corner
- Click See All Options
- Click Settings on the left side
- In the signature box (labeled "E-Mail Signature") type the signature you want to use
- If you want, check the box labeled "Automatically include my signature on messages I send"
- Click Save in the lower right corner

These steps were written specifically for Outlook Web App in Internet Explorer.  The exact steps may vary when you're using other web browsers.  For example, when you use Outlook Web App in Chrome and you click on Options, the signature box comes up right away.
