Spim

Communications Server 2007 R2

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

Spim is unsolicited commercial instant messages or presence subscription requests. While not by itself a compromise of the network, it is annoying in the least, can reduce resource availability and production, and can possibly lead to a compromise of the network. An example of this is users spimming each other by sending requests. Users can block each other to prevent this, but with federation, if a coordinated spim attack is established, this can be difficult to overcome unless you disable federation for the partner.
