by

Sending emails from a different address in Outlook 365 requires making the “From” field visible first. Many users don’t realize this feature is hidden by default, which is why learning how to enable from field in outlook 365 is so important. Once you turn it on, you can send emails as your work alias, a shared mailbox, or even a different account you manage.

This guide walks you through the exact steps to show the From field in Outlook 365. We cover the desktop app, the web version, and even the mobile app. You will also learn how to add additional email addresses and troubleshoot common issues. Let’s get started.

How To Enable From Field In Outlook 365

The From field is not visible when you first open a new email in Outlook 365. Microsoft hides it to keep the interface clean. But enabling it is simple and only takes a few clicks.

Here is the quickest method for the desktop version of Outlook 365:

  1. Open Outlook 365 on your computer.
  2. Click the “New Email” button in the Home tab.
  3. In the new message window, look for the “Options” tab in the ribbon.
  4. Click “Options” and then find the “Show From” button in the Fields group.
  5. Click “Show From.” The From field now appears above the To field.

That is the core answer to how to enable from field in outlook 365. But there is more to know, especially if you use the web version or need to add multiple addresses.

Why The From Field Is Hidden By Default

Microsoft designed Outlook to be simple for most users. Most people only send emails from their primary address. So, hiding the From field reduces clutter. However, power users and professionals often need to send from a different address. This is common for shared mailboxes, distribution lists, or personal aliases.

Enabling the field does not change your default sending address. It just gives you the option to choose a different one per email.

Enable From Field In Outlook 365 Desktop App

The desktop app is the most common version of Outlook 365. The steps are slightly different depending on your version. But the general process is the same.

Step-By-Step For Outlook 365 Desktop (Windows)

Follow these steps carefully. If you miss a step, the field might not appear.

  1. Launch Outlook 365 on your Windows PC.
  2. Click “New Email” from the Home ribbon.
  3. A new message window opens. Go to the “Options” tab at the top.
  4. Look for the “Show From” button. It is usually in the “Fields” section.
  5. Click it. The From field appears right above the To field.
  6. Now you can type a different email address in the From field.

Thats it. The field stays visible for future emails until you hide it again by clicking the same button.

Step-By-Step For Outlook 365 Desktop (Mac)

Mac users have a slightly different interface. But the logic is the same.

  1. Open Outlook for Mac.
  2. Click “New Email” to open a compose window.
  3. Look at the top of the message window. You will see a small dropdown arrow next to the “From” label.
  4. Click that arrow. A dropdown menu appears with your available accounts.
  5. If you do not see the From field at all, go to the “View” menu in the top menu bar.
  6. Select “From Field” from the dropdown. It will toggle it on.

Mac users often miss the View menu option. So check there if the field is not showing.

Enable From Field In Outlook 365 Web Version

The web version of Outlook 365 is also popular. The steps are different from the desktop app. But they are just as easy.

How To Show From Field In Outlook On The Web

Follow these steps for Outlook 365 in your browser:

  1. Go to outlook.office.com and sign in.
  2. Click “New message” in the top left corner.
  3. A new message pane opens on the right side.
  4. Look for the “…” (three dots) icon in the toolbar at the bottom of the pane.
  5. Click it. A menu expands.
  6. Select “Show From” from the menu.
  7. The From field appears above the To field.

Now you can type a different address. If you have multiple accounts added, you can choose from a dropdown list.

Adding A Shared Mailbox To The From Field In Web

If you need to send from a shared mailbox, you must first add it to your Outlook profile. Here is how:

  1. In Outlook on the web, click the gear icon (Settings) in the top right.
  2. Select “View all Outlook settings” at the bottom.
  3. Go to “Mail” > “Shared mailboxes.”
  4. Click “Add a shared mailbox” and enter the email address.
  5. Click “Add.” It appears in your folder list.
  6. Now, when you compose a new email and enable the From field, you can select that shared mailbox.

This is a common need for teams. The shared mailbox must already exist in your organization.

Enable From Field In Outlook 365 Mobile App

The mobile app for iOS and Android does not have a direct “Show From” button. But you can still send from a different address.

For Outlook Mobile (IOS And Android)

Here is the workaround for mobile users:

  1. Open the Outlook app on your phone.
  2. Tap the compose button (pencil icon or plus sign).
  3. In the new message, tap the “From” line. It might show your primary address.
  4. A list of your connected accounts appears. Tap the one you want to use.
  5. If you do not see the From line, tap the three dots (More) in the compose screen.
  6. Look for “Show From” or “From” in the menu.

Not all mobile versions have the same options. If you cannot find it, use the desktop or web version to set up the From field first.

Adding Additional Email Addresses To The From Field

Enabling the field is step one. Step two is adding the addresses you want to send from.

How To Add An Alias Or Shared Mailbox

You can send from any email address that you have permission to use. This includes:

  • Your own alias (e.g., firstname.lastname@company.com vs. info@company.com)
  • A shared mailbox (e.g., support@company.com)
  • Another account you own (e.g., personal Gmail)

To add a shared mailbox in the desktop app:

  1. Go to File > Account Settings > Account Settings.
  2. Select your email account and click “Change.”
  3. Click “More Settings” > “Advanced.”
  4. Under “Open these additional mailboxes,” click “Add.”
  5. Type the shared mailbox email and click OK.
  6. Restart Outlook. The mailbox appears in your folder list.
  7. Now, when you compose an email and enable the From field, you can choose that mailbox.

For personal accounts, you can add them directly in the From field dropdown by selecting “Other Email Address…” and typing it in.

Sending From A Different Address Without Adding It

You can also type any email address directly into the From field. But Outlook will ask you to confirm that you own that address. It sends a verification email. Once verified, you can use it freely.

This is useful for temporary situations. But for regular use, it is better to add the address to your account.

Common Problems And Fixes

Sometimes the From field does not appear even after you follow the steps. Here are common issues and how to fix them.

From Field Button Is Greyed Out

If the “Show From” button is greyed out in the desktop app, you might be using an older version. Update Outlook 365 to the latest version. Also, check if you are in a read-only mode or if your account has restrictions.

From Field Shows But Cannot Type

If the field appears but you cannot type in it, you might not have permission. For shared mailboxes, you need “Send As” or “Send on Behalf” permissions. Contact your IT admin to grant these rights.

From Field Disappears After Sending

The From field should stay visible once enabled. If it disappears, you might have closed the compose window and opened a new one. The setting is per session in some versions. Re-enable it each time you need it.

Web Version Not Showing The Option

If the three-dot menu does not have “Show From,” try refreshing the page. Also, clear your browser cache. Some browsers block certain features. Use Edge or Chrome for best results.

Best Practices For Using The From Field

Using the From field correctly is important for professional communication.

  • Always double-check the From address before sending. It is easy to send from the wrong account.
  • Use a clear signature that matches the sending address. If you send from a shared mailbox, use that mailbox’s signature.
  • Do not spoof addresses. Only send from addresses you own or have permission to use. This prevents your emails from being marked as spam.
  • For replies, the From field usually defaults to the original sender’s address. Be careful when replying to a thread that was sent from a shared mailbox.
