This normally means the user name or password are wrong.

It is best to say the version number.  It might, for example, be the 
latest on a particular OS, but not the latest version, and someone 
reading this in the future, may assume it is the most recent one at that

Before you can expect a fix, you need to provide enough information to 
identify the cause of the problem; on the information provided, 
providing the wrong user or password is the most likely cause.  Assuming 
MS Windows, a cut and paste of the debug window may help.  NB this is an 
archived, public mailing list.

With proprietary protocols, like MSN, it can also happen that they are 
changed in ways that takes a long time to reverse engineer, although, if 
that had happened, one would expect a lot of people to be reporting

Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
