Persistent password error when configuring a mailbox in Outlook or Foxmail

Scenario

When you configure a free personal Alibaba Cloud mailbox in Outlook or Foxmail, a username and password error message repeatedly appears, even though you entered the correct password.

In this case, check the webmail settings page to confirm that the Post Office Protocol (POP)/Internet Message Access Protocol (IMAP) feature is enabled. If this feature is disabled, enable it.

If the feature is enabled, check whether you entered the full username. The username must include the domain, such as @aliyun.com.
