If you’ve already set up an IMAP email account in Outlook 2016 or later for Mac and you want to make sure the settings are correct, or change the name other people see when you send them mail, this page explains how to do so.

Before you continue, you should enter your email address (the address you want to set up in Outlook) in the box above. Entering your email address makes sure that the instructions below are correct.

1. Start Outlook.

If Outlook isn’t already running, start it now.

2. Select the account.

Open the Tools menu, then click Accounts.

Select your account in the list on the left-hand side of the window.

3. Verify the basic account settings.

The window should look like this:

Account settings

Although the “Account Description”, “Full Name” and the “Password” will be different, everything else should be as shown above. In particular, these must be exactly right:

  • E-mail address: your email address
  • User name: your email address (all lowercase)
  • Incoming server: : 993
  • Use SSL to connect (recommended) should be checked
  • Outgoing server: : 465
  • Use SSL to connect (recommended) should be checked

After verifying these settings, click the More Options button.

4. Configure outgoing mail authentication

Select Use Incoming Server Info for the Authentication field:

Use Incoming Server Info

Then click OK.

You are done configuring Outlook. You can now close the “Accounts” window.

5. Test the settings.

Send yourself a test message. Doing so will test both sending and receiving.

Still having trouble?

We’ve heard reports of Outlook database corruption on the computer itself causing problems like crashes in Outlook, or problems synchronizing folders.

Although fixing this is outside the scope of what we can help with in detail (Microsoft should be able to assist), one tip that sometimes helps is rebuilding the Office database on your computer.

Do some people see duplicate images in messages you send?

Outlook for Mac has a bug that can cause duplicated images, unfortunately. It’s not caused by a problem on your computer, or our servers.
