From the Dark Side--Microsoft Messenger for the Mac v5.0 is Out

but not yet available at publication time from Microsoft's Web page. If you are locked in a near-brain-dead, Widows-only IT environment that merely tolerates the presence of a Mac, then this update may be for you.

According to Microsoft, Messenger for Mac 5.0 introduces tabbed viewing, a new approach for Mac customers who use instant messaging for work and for play. Users may simultaneously access corporate and personal Messenger accounts and set a unique user status on each. The personal tab allows users to instant message (IM) with friends and family, while support for Microsoft Office Live Communications Server 2005 enables enterprise customers to IM in a security-enhanced manner via the corporate tab with colleagues inside and out the network.
