Steps to reproduce the behavior:
- Open config for outbound email account
- Send mails via: SMTP
- Host: smtp.office365.com
- User: mycorpemail@example.com
- Password: my_corp_email_password
- Port: 587
- Click Continue
Update: issue resolved!
I updated it here for anyone who has the similar issue like me:
- Double check your credentials
- If your credentials are correct, you may get this error when you change your sending email address from one to another. The verification would fail because the old sender email address and the new one were mismatched.
- You need to change your sender email address (Email Address) right under the Outbound.section first. Then change your IMAP and SMTP should work.
