Follow these steps to fix the problem:

  1. Enable SMTP and then wait for an hour. Waiting for an hour is a crucial step. This allows Microsoft to propagate the changes and share new tokens with us.

    Here's the official Microsoft guide on it: https://aka.ms/smtp_auth_disabled or you can follow these steps:

    1. Login to your admin console and from this link https://admin.microsoft.com/adminportal/home#/users - select the account

    2. Click Mail in the flyout that appears, and then click Manage email apps

    3. Verify the Authenticated SMTP setting is enabled:

    4. Save changes

  2. After one hour, remove accounts from Instantly and then connect them again.

Click on your account's three dots in Instantly and choose Remove Account:

In case you are getting the error "Your account already exists" when trying to add it, you need to sign in to Instantly from the Incognito window.
