Issue adding Workmail account to Smartlead Tool

It seems you're encountering an authentication issue while trying to add your Amazon WorkMail account to Smartlead. Based on the information provided, there are a few things to check and consider:

1. Personal Access Token: You're on the right track using a personal access token as the password. This is the correct approach when multi-factor authentication (MFA) is enabled for your WorkMail account. Make sure you've generated this token correctly from the Amazon WorkMail web client.

2. Token Visibility: Remember that you can only view and copy your personal access token once when creating it in Amazon WorkMail. If you've lost or forgotten the token, you'll need to generate a new one.

3. Token Status and Expiration: Verify that your personal access token is still active and hasn't expired. By default, tokens are valid for 365 days, but this can be configured differently by your administrator.

4. Region Consistency: Ensure that you're using the SMTP and IMAP hosts for the correct AWS Region. The hosts you've provided (smtp.mail.us-west-2.awsapps.com and imap.mail.us-west-2.awsapps.com) are for the US West (Oregon) region. Make sure this matches the region where your WorkMail organization is set up.

5. Username Format: Double-check that you're using the correct username format. It should typically be your full email address.

6. IAM Identity Center Association: Confirm with your administrator that your Amazon WorkMail user is properly associated with an IAM Identity Center user authorized to access the Amazon WorkMail application.

If you've verified all these points and are still experiencing issues, you may want to try generating a new personal access token. If the problem persists, it would be advisable to contact your AWS administrator for further assistance, as there might be specific configurations or restrictions in place for your organization.
