In September, we began asking users on 8.1 clients to upgrade to the latest version of messenger to ensure that they had the most up to-date and secure release.  (see post)

Starting today, users on version 8.5 will also be required to upgrade before they can sign-in to the service.  Starting on the November 9th, users on Messenger 2009 (version 14) will need to upgrade their clients too.  Users who have already installed the latest version, which was released Aug 18th 2009 (Build: 14.0.8089.726),  will not be required to upgrade.

If you are using Messenger 2009 and are curious what version you have, you can go to the Help –> About Menu.

If you have any issues or questions during the upgrade process, here are the places you can go to get some answers.

Note: Users on Windows XP will need to ensure that they have installed Service Pack 2 (SP2) or higher, otherwise the upgrade will not work.  Instructions to install the latest Service Pack (SP3) can be found here.  Additionally, here is more information about the system requirements.
