2. The password window keeps coming up, and I cannot retrieve any email. ( Get this error even though you have not changed your password )
There are several possibilities for this error.
  • Your email account name and password are entered incorrectly.

First, please open the properties window and delete the email account name and email password and re-enter them. Deleting and re-entering allows the computer to realize the email account name and password again, which may solve the problem.
If the problem can not be solved, the server may be locked. Please try logging on to the server after 30 minutes. When an interruption occurs in the middle of retrieving or when the connection is cut off during retrieving, the email account will remain locked, which will not, allow the session to take place.
Normally, this error will be automatically cancelled in about 30 minutes, so please be patient. There is a case where the message cannot be retrieved into your system for several times. If this occurs, please visit the following URL, where you can view and delete the messages on the Web.

8. The email is not readable because it turns to weird characters.
In the case of an attachment file, in order for the receiver to read the file, the encoding that the sender used for the file and the decoding that the receiver used to receive the file will have to be identical. If you can not read the file, please check the sender's encoding.
Further, newer versions of email software are corresponding to a Base 64 model, which will enable you to send and receive files freely if the sender uses a Base 64 model to send the file.
[ Typical Encoding Models ]
Base 64 --- Used commonly for Windows
uuencode --- Used commonly for UNIX
Binhex, apple double --- Used commonly for Macintosh
