Situation: When a new user login Mitel Connect, she receives this message: Either your username, password, or server didn’t match.
Troubleshooting: 1. Since the Domain already has the domain name entered, don’t use domain in username. The correct username is username. If you enter domainname\username, that may not work.
2. Sometimes, email as suername doesn’t work.
3. Also make sure you sync the AD under General.
