1. These do not use secure login, so we recommend using a separate password, which you can manage in your Legacy Settings.

2. MSN 5/6/7/8 and WLM '09 work on Windows XP and Vista, but have issues logging in due to known incompatibilities with the HTTPS protocols between the server and the affected OSes and us being unable to tweak our setup to effectively support those systems. Refer to this guide for a fix.

3. MSN 7 supports receiving offline messages (OIMs), but can't send them to others.

4. Only 8.1.0178 and 8.5 are known to work; others might not.

5. While WLM 8 and '09 can work on Windows XP, they have some incompatibilities out of the box because of the way older systems handle SSL, as such, we recommend using a newer operating system or trying the same fix as MSN 5/6/7/8 (point 2)

6. MSN 1 only supports login on @hotmail.com, however simply enter your username without @escargot.chat and ignore the @hotmail.com part.
