Question details

Users are unable to successfully add or sync their Microsoft Exchange or Hotmail accounts in the macOS Mail app due to a password verification failure, despite the credentials functioning properly on web browsers.

Product: macOS Mail
Device & OS: macOS
Scenario: Adding or syncing a Microsoft email account (Exchange or Hotmail) within the Apple Mail application.
Observed behavior: The macOS Mail app displays an error message stating it cannot verify the account name or password, preventing the email account from connecting.

Before you start

Ensure that your Mac is connected to a stable internet network and verify your credentials by logging into your Exchange or Hotmail account through a web browser to confirm the password is correct.

Solution 1Recommended

Remove and Re-add the Email Account Using Modern Authentication

Re-adding the account forces macOS to use modern web-based authentication (OAuth), which usually resolves strict verification errors.

Older account configurations might rely on outdated authentication methods that Microsoft no longer supports. By removing and setting up the account as a 'Microsoft Exchange' account, macOS will trigger a secure browser-like pop-up for login, bypassing the native macOS password prompt limitations.

Open Internet Accounts

Click the Apple menu in the top-left corner of your screen, select 'System Settings' (or 'System Preferences'), and click on 'Internet Accounts'.

Delete the Problematic Account

Select the Exchange or Hotmail account that is failing to verify. Click the 'Delete Account' button (or the minus '-' icon) to remove it from your Mac.

Add a New Exchange Account

Click 'Add Account' and specifically select 'Microsoft Exchange' from the provider list, even if you are using a Hotmail or Outlook.com address.

Sign In Securely

Enter your email address and click 'Sign In'. When prompted, choose 'Sign In' again to authenticate via Microsoft's secure login screen instead of configuring manually.

Authentication Successful: Using the 'Sign In' button instead of 'Configure Manually' ensures that two-factor authentication and modern security protocols are properly handled.

Solution 2

Generate and Use an App Password

If you are using an older version of macOS that does not support modern Microsoft authentication, you will need to bypass the standard password using an App Password.

Frequently Asked Questions

Why does my Exchange password work in the browser but fail in Apple Mail?

Web browsers use Microsoft's modern web authentication natively. Apple Mail, especially if configured using older methods or on older macOS versions, may attempt to use legacy authentication protocols that Microsoft blocks for security reasons, resulting in a verification error.

Does macOS Mail support two-factor authentication for Hotmail?

Yes, modern versions of macOS Mail support two-factor authentication (OAuth) for Microsoft accounts. You must select 'Microsoft Exchange' as the account type when setting it up to trigger the secure login prompt. If you are on an older OS, you will need an App Password instead.

How do I force Apple Mail to sync my Exchange account after a password change?

You can go to System Settings > Internet Accounts, select your Exchange account, and update the password. If it refuses to verify, the most reliable method is to delete the account from Internet Accounts and add it back to refresh the authentication tokens completely.
