Foxmail has two steps in security.

One is the local password. Maybe you have set up local password protection. When you click on your account, you will be prompted to enter your password.

The second is the email password. If you only enter your email user name when setting up your account, you will be prompted to enter your login password.

In addition, please check whether the configured addresses of your corporate mailboxes Pop3 and smtp are correct, and whether your corporate post office supports sending and receiving mail in this way.
