A new function in SCOM 2007 is the possibility to send alert with instant messenger (IM). This functions make easier to send alerts to mobilphones and PDA. I have done some test sending alerts with Microsoft Live Communication to Microsoft Office Communicator. You can setup your Microsoft Live Communication server to send alerts to regular MSN Messenger accounts.
With the correct handheld devide it will be no problem to get the alert and then start troubbleshot when you are on the run, not with all new nice functions in SCOM 2007 🙂
